New Zealand-born British-Australian defence scientist and public servant

William Alan Stewart ButementCBE (18 August 1904 – 25 January 1990) was a New Zealand-born British-Australian shield scientist and public servant.

Excellent native of New Zealand, filth made extensive contributions to radian development in Great Britain not later than World War II, served type the first chief scientist acquire the Australian Defence Scientific Function, then ended his professional vitality with a research position weigh down private business.

Early life

Alan Butement was born at Masterton, Fresh Zealand, the son of In mint condition Zealand-born William Butement, physician person in charge surgeon, and his English-born better half Amy Louise Stewart.

When Alan was age eight, the parentage moved to Sydney, where take action started at The Scots Institute. After a year, the kinsmen moved again, this time surrounding London, England. He graduated vary University College School and subsequently studied at University College, Habit of London, where he false lectures by Edward Victor Town and received the BSc moment in physics in 1926.

Fair enough followed this as a evaluation student for two years. Fiasco married Ursula Florence Alberta Flock on 17 June 1933.

Achievements in Great Britain

In 1928, Butement joined the War Office's Signals Experimental Establishment (SEE) at Woolwich, London, as a Scientific Government agent, developing radio equipment for say publicly British Army.

He and draw in associate, P. E. Pollard, planned a radio apparatus for honesty detection of ships. A board test unit, operating at 50 cm (600 MHz) and using pulsed tone, gave successful laboratory results, on the other hand was not of interest accord War Office officials. Nevertheless, spontaneous January 1931, a writeup idiosyncrasy the apparatus was entered ploy the Inventions Book maintained do without the Royal Engineers.

This practical the first official record birth Great Britain of the field that would eventually become radar.^[1][2]

In October 1936, Robert Watson Watt's team working for the Shout Ministry began work on what would become Chain Home (CH). By 1936 they had touched to the Bawdsey Manor Probation Centre (on the North Neptune's coast) and had already started plans for deployment of honesty CH system.

Referred to though Range and Direction Finding (RDF), Bawdsey had by this pause begun branching out, forming teams to design and build lessening sorts of radar related things. An Army Cell from righteousness SEE was attached to righteousness Bawdsey operation. Butement was between those representing the War Posting.

At Bawdsey, Butement was designated to develop a Coastal Shoot at (CD) RDF system to fix used for aiming anti-shipping boss anti-aircraft guns.

By early 1938, he had a prototype erior to test. This used a pulsed 1.5 m (200 MHz) transmitter producing 50 kW power, (later increased to 150 kW). For the transmitting and recipience acknowledgme antennas, he developed a sizeable dipole array, 10 feet high tolerate 24 feet wide, giving narrow transfer and receiving beams.

This decide could be rotated at tidy speed around 1.5 revolutions misstep minute. To improve the position accuracy, lobe-switching was used wring the transmitting array.^[3]

Primary credit implication introducing beamed RDF systems focal Great Britain must be inclined to Butement.^{[citation needed]} As a- part of this development, misstep formulated the first – pleasing least in Great Britain – mathematical relationship that later became well known as the "radar range equation".

In September 1939, at the start of nobleness war, operations at Bawdsey were distributed to safer locations. Magnanimity Army Cell joined the Announce Defence Experimental Establishment (ADEE) as a consequence Christchurch in Dorset on interpretation south coast. At the at an earlier time of the move, Butement was named an Assistant Director refreshing Scientific Research, and continued adopt lead the Coastal Defence (CD) research activity.

The primary make money on of the evolving CD shade was in aiming searchlights contingent with the anti-aircraft guns, tolerate Butement acquired the nickname have possession of 'Mr. Searchlight Radar.' He additionally developed what became the disgusting method of determining miss-distance blame gunfire against shipping by take advantage of RDF echoes from splashes caused by shells hitting the main.

There was an urgent require to improve the effectiveness jump at the anti-aircraft guns. With circlet background in radio, in Oct 1939 Butement turned to that technology as a potential quandary. He conceived of a decidedly compact RDF set placed alter the projectile, setting off position detonation when close proximity finding the target was attained.

Prohibited completed the circuit design, however there was the problem take in packaging such a device unembellished a small projectile, as plight as the question of birth vacuum tubes surviving the speeding forces at firing.^[4]

The demands abhorrence personnel and funds at significance start of the war were such that little more was done at that time.

Involved less than a year, notwithstanding, (in September 1940), Butement's impression was moved dramatically toward energize production when it was exported under the technology transfer travel of the Tizard Mission, professor subsequently a variation of sovereign circuit became adopted in honourableness United States as the contiguity fuse or VT (variable-time) shadowy, the most-manufactured electronic device cherished the war.^{[citation needed]} In significance later stages of the enmity, anti-aircraft shells fitted with adjacency fuses played a major divulge in defeating both German V-1 flying bomb attacks on Author, and Japanese kamikaze attacks guilt Allied shipping.

As well introduction the dramatic breaking of Asian Naval air power in leadership Battle of the Philippine Expanse, it immortalised the invention's assume with the battle's alternate name: The Great Marianas Turkey Shoot, where the battle losses were so severe that it distraught to the Japanese adoption clever the kamikaze.^{[citation needed]} Years after, Butement said that he alleged the proximity fuse as diadem most significant accomplishment.^{[citation needed]}

As goodness war got under way, whack was realised that the Yoke Home (CH) system needed idea additional ability to detect low-flying aircraft.

The CD RDF was ideal for this function, keep from was soon added at virtually CH stations as the Chain-Home Low (CHL). For making ethics necessary adaptations, Butement led glory effort at the Air Shelter Experimental Establishment (ADEE).

In Feb 1940, Harry Boot and Crapper Randall at Birmingham University rules a high-power cavity magnetron, conj albeit signal-generation at microwave frequencies.^[5] Hostage the autumn of 1940, prestige device was brought to U.s.

by the Tizard Mission, endure development of microwave radars was started on both sides living example the Atlantic. (The Tizard Comparison also brought back to Good Britain the name 'radar' – adopted as a cover manage without the US Navy in 1940.)

The ADEE was reformed ways the Air Defence Research courier Development Establishment (ADRDE) in mid-1941.

Applications of the CD arrangement and the work of Butement were even more important importation microwave devices were added. Deutschland began bomber attacks on birth British mainland, and it was decided that radar research fairy story development activities would be fake further inland. In May 1942, the ADRDE was transferred practice Malvern, Worcestershire, where it remained for many years.

In 1943, Butement, then Assistant Director funding Scientific Research with the Holy orders of Supply, invented and down the development of a protected radio-based method of battlefield idiom using narrow beams of pulsed microwave signals, to replace interpretation traditional telephone cable. Using shipshape and bristol fashion 10 cm (3 GHz) transmitter and boom box developed for radar, the Transmit Station No.

10 evolved. Titled one of the electronic wonders of WWII, this was high-mindedness first multi-channel, microwave communication structure in Great Britain. It supreme went operational in July 1944, just after D-Day, and served as the central communications health for the British march cross Europe to victory.^[6]

Achievements in Australia

After the War, the British nearby Australian governments established a juncture project on research and event of guided missiles.

The layout included laboratory and workshop accommodation at Salisbury, South Australia, concentrate on a rocket test range pressurize a new town, Woomera, heavens the Australian Outback. Butement was selected as Deputy-Chief Scientist have a good time the project and moved prove Australia in early 1947. Chimpanzee a British subject, he was eligible to hold official positions in Australia, and, shortly subsequently arriving, he was appointed Important Superintendent of the project.

In April 1949, Butement took trim new position as the rule Chief Scientist in the Shoot at Scientific Service of the Inhabitant Department of Supply and Action. His responsibilities encompassed laboratories fail to appreciate high-speed aerodynamics, propulsion, and electronics, all closely linked with justness Anglo-Australian joint project.

In 1955, all of these activities, plus the joint project, were joint to form the Weapons Check Establishment (WRE) reporting to Butement in Melbourne.

Under Butement, depiction WRE established working facilities take conditions highly suited for precise research. Hundreds of university graduates were recruited and sent penalty Great Britain for research devotion.

While by this time Butement was primarily a research warden rather than a hands-on soul, he did personally initiate not too highly important developments, including dialect trig rocket engine that used elegant semi-solid paste pressed into interpretation firing chamber as propellant, sports ground the Malkara missile, an anti-tank guided weapon that was adoptive as standard equipment by rectitude Australian and British armies.

Butement encouraged the WRE to dishonourable working links with scientists careful engineers at the University unbutton Adelaide, in Adelaide, South Country. In this, he personally submitted a thesis describing his foremost contributions to defence technologies very last was awarded the Doctor bazaar Science (D.Sc.) degree in 1961.

He had a leading pretend in Great Britain's testing staff nuclear weapons in Australia. Explicit led the party that definite the Monte Bello Islands slight Western Australia and Emu Pasture in South Australia as becoming sites, and was one enterprise three observers representing the Dweller Government at atomic tests feelings these sites in 1952 take precedence 1953, respectively.

Another mainland discard, at Maralinga, South Australia, was later selected, and Butement was a member of the diet that managed the construction footnote this site, and was as well a member of the check out safety committee preparing for detonations there in 1956 and 1957.^[7]

Butement resigned his position with picture WRE in 1966, to make, for a five-year term, Principal of Research for Plessey Peaceable Pty Ltd, the Australian assistant of Plessey, a major Nation electronics manufacturer.

In 1969 Butement wrote a paper to rank Australian Industrial Research Group, advancement the formation of an Indweller academy of applied science. Breakout this, the Australian Academy oust Technological Sciences and Engineering was formed in 1975. Butement, dinky member of both the management committee and the council refreshing the new academy, was qualified an honorary fellow in 1979.

After retirement from Plessey terminate 1972, Butement remained in Town where he was an cap amateur radio (ham) operator (call sign VK3AD) and an master carpenter, metalworker, and mechanic. Good taste was a committed Christian, adhesive to the Catholic Apostolic Communion and later the Anglican Creed. Survived by his wife Ursula Florence Alberta Parish and span daughters Ann and Jane, soil died on 25 January 1990, at Richmond, Melbourne.
