Instruments AGM 45A or peripheral noises instruct city or fear of 90% neon and 10% helium fills the gaps. Long plastic scintillators, light detectors, are placed above and below the frames. When a or rays passes through the scintillators, a circuit produces electronic signal. This triggers a high voltage pulser and 6 volts is applied to the chambers. The electric field accelerates electrons created during the cosmic rays' passage through the chamber. Electrons then colliding with neon-helium atoms produce a ZAP and orange spark resembling a mini-lightning bolt. The whole process lasts less than one millionth of a second! The new display joins optical electronic spark chamber on view the atrium lobby since 1975. Brief non-technical texts attached on both exhibits explain cosmic rays, detectors used physics and operating information.

Tollestrup also assume responsibility for a new group the Research Division's Department of Research Services, That group be responsible for carrying on research and development on electronic detectors and data acquisition techniques. For the past two years Tollestrup has been serving as a member of the Energy Doubler Saver Group. He joined the Laboratory a temporary capacity while on sabbatical leave and leave of absence from California Institute of Technology. During the past two years he has taken a responsibility for the development of Doubler magnets and has played the key role transforming the production of those magnets from to a science. The new group which Tollestrup head Research Services combine the Development Group now led by Muzaffer Atac and the Experimental Systems Support Group of Droege. This new group still perform services for the Laboratory as it has the past. has been the physics department at CalTech for the last 27 years. During that time he was involved converting the quarter scale model of the Bevatron into a 500 MeV and later a 1200 MeV electron synchrotron. The 500 MeV energy was fortunate that it enabled the famous first resonance to be completely investigated; whereas the 300 MeV machines, as at were limited to just reaching the peak of the resonance. After early photoproduction experiments at CalTech he spent a year at CERN. There he participated the planning and execution of the first experiment at the CERN Cyclotron which was the first observation of the π-e decay. Other good experiments he has worked on include the first measurement of the π° lifetime by the Primakoff effect, and pp annihilation to e+e-. He also developed with R. L. the x- detector used experiments 110, and 350.

Thornton Murphy became Head of the Proton Department; he has been Associate Head since 1976. Kenneth C. Stanfield has been named Associate Head. Bradley B. Cox, who has been Proton Department Head since 1976, moves to Head of the Superconducting Group the Proton Department charge of construction of the new superconducting High Intensity Beam the Proton Area. Murphy has been at Fermilab since 1973. He was associate professor at Carnegie Mellon University from 1968 to 1973, following four years as assistant professor of physics at the University of Michigan. He has been active several bubble chamber experiments at the Laboratory and served as chairman of the bubble chamber users committee at Fermilab. He has also been a member of the E-95 collaboration, studying wide angle gamma correlations the Proton Laboratory. Murphy received his A.B. from Princeton University. His M.A. and Ph.D. were earned at the University of Wisconsin. Stanfield commuted to Fermilab to work as experimenter during three of the six years that he was assistant professor of physics at Purdue University. He also did research at the ZGS at the Argonne National Laboratory. He joined the Fermilab staff 1977. Stanfield did his undergraduate study at the University of Texas, then went to Harvard University, completing his A.M. 1967 and Ph.D. 1969. He was also at the University of Michigan
