Injection septum magnets for the Loma Linda medical accelerator

The injection beamline runs over the last magnet before a long straight section and is then displaced downward 55.88 cm to the accelerator beamline. The displacement is magnetic and the final deflection onto the synchrotron orbit is by an electric kicker. The first component, the reverse septum magnet, bends the injection beam 25)degree) downward. This is followed by the injection septum (20)degree) bend upward) and the final injection kicker (5)degree) bend upward). The septum magnets produce a peak field of 3.4 K gauss at a current of 28,000 amperes within a 0.1 msec long pulse. The electric kicker produces a field of 7.3 KV/cm with a pulse length of 0.0011 msec. The septum magnets are similar to each other in construction with a bending radium of 72.7 cm. The curvature is required to increase the effective aperture. Each magnet has a single-turn copper coil bonded to a stainless steel plate for reinforcement. This eliminates insulating material, which could be subject to radiation damage, at the septum. The stainless steel plate is welded to the magnet laminations. The current is confined to the septum by the insulation between the laminations, which are a standard core material. The total septum thickness with …

Central Calorimeter Transporter Cart Design (open access)

Central Calorimeter Transporter Cart Design

The purpose of the cryostat transporter cart is to provide a means of rolling the CC cryostat in and out of a building, and to proyide a means of support for the cryostat while it is being worked on. The constraints on the cart are: (1) There should be a minimum amount of clearance between the cryostat and the ground, in order to be able to roll the cart and cryostat into a building; (2) The cart must be able to support the weight of the cryostat as well as the weight of approximately 4,000 gallons of liquid nitrogen; and (3) The cart must allow access to the underside of the cryostat for work that must be done. This report will address the design of the transporter cart, as well as any additional equipment needed to accomplish the above mentioned tasks.
