Preliminary result on Quarter wave transformer simulation a short lens with a high magnetic field and a long solenoidal magnetic field. Field profile of quarter wave transformer

1. Let current in matching solenoid to be zero and solve Poisson for magnetic field map of bulking and focusing solenoid. Length of solenoid, all separation and all aperture is variable. Bulking Focusing Matching Magnetic field profile: Superposition of two field maps.

2. Let current in focusing and bulking solenoid to be zero and solve for the field map of matching solenoid.

On axis Bz profile Scale and combine the field maps and do beam dynamic simulation using PARMELA. Tracking e+ upto ~125MeV Accelerator begins

Conditions and assumptions Combine the field maps and then do beam dynamic simulation using PARMELA. Tracking e+ up to ~125MeV B field is fixed at 0.5T after quarter wave transformer. The first Linac section starts at 20cm as in RDR. The longitudinal center of target is the center between focusing and bucking solenoids. The capture efficiency is calculated at end of the TAP, ~125MeV, using phase cut +/- 7.5 degrees, Energy cut 50MeV. For reference, the capture efficiency calculated using same cut for case with OMD as 5T-0.5 in 20cm, we have ~35% for immersed case and ~26% for non- immersed case

Capture efficiency as function of length of focusing solenoid. Max B field on axis is ~1T. Gap between bucking and focusing is at 2cm. Separation between focusing and matching is 0.

Capture as function of focusing field Colors represent different thickness of the focusing solenoid. The thinner focusing solenoid has better performance.

The smaller separation between matching and focusing, the better the performance Capturing efficient as a function of distance between matching and focusing solenoids
