Technical Details of the Elliott 152 and 153
Appendix 1 Technical Details of the Elliott 152 and 153 Introduction The Elliott 152 computer was part of the Admiralty’s MRS5 (medium range system 5) naval gunnery project, described in Chap. 2. The Elliott 153 computer, also known as the D/F (direction-finding) computer, was built for GCHQ and the Admiralty as described in Chap. 3. The information in this appendix is intended to supplement the overall descriptions of the machines as given in Chaps. 2 and 3. A1.1 The Elliott 152 Work on the MRS5 contract at Borehamwood began in October 1946 and was essen- tially finished in 1950. Novel target-tracking radar was at the heart of the project, the radar being synchronized to the computer’s clock. In his enthusiasm for perfecting the radar technology, John Coales seems to have spent little time on what we would now call an overall systems design. When Harry Carpenter joined the staff of the Computing Division at Borehamwood on 1 January 1949, he recalls that nobody had yet defined the way in which the control program, running on the 152 computer, would interface with guns and radar. Furthermore, nobody yet appeared to be working on the computational algorithms necessary for three-dimensional trajectory predic- tion. As for the guns that the MRS5 system was intended to control, not even the basic ballistics parameters seemed to be known with any accuracy at Borehamwood [1, 2]. A1.1.1 Communication and Data-Rate The physical separation, between radar in the Borehamwood car park and digital computer in the laboratory, necessitated an interconnecting cable of about 150 m in length. -

It will be possible to store muon beams with central momentum from 1 GeV/c to 6 GeV/c with a momentum acceptance of 16%. The nuSTORM facility will have the capability to: ,- ,- • Serve a definitive neutrino-nucleus scattering programme with uniquely well-characterised ν e and ν µ beams; • Allow searches for light sterile neutrinos with the exquisite sensitivity necessary to go beyond the reach of the FNAL Short Baseline Neutrino programme; and • Provide the technology test-bed required for the development of muon beams capable of serving as the basis for a multi-TeV lepton-antilepton (muon) collider. -

Description of Ph.D. Project in EXSS for Oct 2021 Entry
Description of Ph.D. project in EXSS for Oct 2021 Entry Project title: Quantum Cascade Laser s-SNOM for intracellular imaging Principal Prof Chris Phillips Project No: CCP_1 Supervisor: Email: [email protected] Telephone x47575 Other Dr Holger Auner, Prof Alexandra Porter, Prof Charles Coombes. supervisors: Aims of the project: Very recently we gave found out how to use a Solid- State near field imaging technique, so- called s-SNOM, to look inside cells for the first time. It beats the diffraction limits of ordinary microscopy by a factor of ~3000, and the spatial resolution it gives (~3nm) already rivals the very best of electron microscopy at a fraction of the time effort and cost. We believe it has the potential to transform the biomedical sciences. We have shown how it can image the organelles inside a cell optically for the first time first time ever. Also , because it works at mid-IR wavelengths where chemical bonds have characteristic vibrational absorption bands that give them spectral “fingerprints” , the technique can be used to provide nanoscal chemical maps that, e.g. reveal where drugs bind inside the cell. The initial aims of the project will be to trail and develop the technology with Imperial cinicians, with a focus on themes, (1) the pathology pf Breast Cancer, (2) Drug resistance in multiple myeloma, and (3) the nanoscale causes of osteporosis. However, the potential applications are limitless and we will likely establish more collaborations as the programme progresses. Also Recent developments in the field of quantum imaging have demonstrated new methods of imaging objects by detecting photons that have not actually interacted with it. -

SUTHERLAND, CBE, MA, FIEE Research Division. After an initial period formerly at Marconi Radar Systems developing special receivers for wartime directionĆfinding systems, he worked exclusively on military and civil radar systems until his retirement in 1986. He was the first Technical Director of the newlyĆformed Marconi Radar Systems Ltd. in 1969 and in the subsequent The earliest concept of radar in the Marconi years he took responsibility for all Company Company came on 20th June 1922 when development at both Chelmsford and Leicester, as well as - for a period - all Company Guglielmo Marconi addressed a joint meeting in production. Latterly he had direct control of the Radar Research Laboratory at Baddow. He was New York of the American Institute of Electrical appointed OBE in 1986.

CHAIN HOME TOWER at Great Baddow - Response to Case #: 1454834
CHAIN HOME TOWER at Great Baddow - Response to case #: 1454834 My interest in this case stems from my family history. My father Bruce Neale, later to become Chief Engineer at Marconi Radar, was an RAF Warrant Officer in WW2 and worked on CH and later precision bombing aids such as OBOE and GEE. This is how he met my mother, a WAAF Sergeant who initially monitored the CH oscilloscope traces looking for the reflections of incoming German aircraft – some signals which were probably launched from that very RAF Canewdon (now Baddow) tower! Below is the remarkable photograph of my ‘to be’ parents actually in an Oboe station in 1943 courtesy of Colin Latham’s book ‘Radar-A wartime Miracle’. I have always regarded myself as a child of Radar! The ‘CH-The First Operational Radar’ article ( www.radarpages.co.uk/mob/ch/chainhome.htm ) was written by my father for the GEC Journal, a special edition commemorating the 50th anniversary of Robert Watson Watt and Arnold Wilkins’ demonstration of the feasibility of detecting radio reflections from aircraft at Weedon, Northamptonshire in 1935. My parents got to know Arnold Wilkins and his wife towards the end of all of their lives. The article has become the reference paper for anybody interested in the CH Radar System and he gave many lectures on the subject. My father had joined the Marconi Company in the early 1950’s when they won the contract for project ROTOR to upgrade the UK WW2 Early Warning Radar Network which included the later versions of CH and he officially retired in 1985 although he continued as a consultant until his death. -
