In Memoriam: A Tribute to Bob Shafer | |
|
||
Robert E. (Bob) Shafer, a leader in the field of beam instrumentation, died on November 11, 2012. His distinguished career spanned decades at major U.S. facilities, including Fermi National Laboratory and Los Alamos National Laboratory. He taught a course on Beam Position Monitoring at the U.S. Particle Accelerator School. His text for that course is a seminal paper on the subject. Bob was one of the founding members of the Beam Instrumentation Workshop, a predecessor of IBIC. | ||

TUPD04 | Third Generation Residual Gas Ionization Profile Monitors at Fermilab. | 408 |
|

Funding: DOE The latest generation of IPM's installed in the Fermilab Main Injector and Recycler incorporate a 1 kG permanent magnet, a newly designed high-gain, rad-tolerant preamp, and a control grid to moderate the charge that is allowed to arrive on the anode pick-up strips. The control grid is intended to select a single Booster batch measurement per turn. Initially it is being used to allow for a faster turn-on of a single, high-intensity cycle in either machine. The expectation is that this will extend the Micro Channel Plate lifetime, which is the high-cost consumable in the measurement system. We discuss the new design and data acquired with this system. |
