Solenoid Effects and Correction in RHIC
- Brookhaven National Lab. (BNL), Upton, NY (United States)
The possible orbit effects due to the STAR solenoid in RHIC have been studied. The linear coupling effects due to the solenoid have been found to be small compared to the effects due to the random skew quadrupole field errors in the magnets. It does not appear necessary to add any additional skew quadrupole correctors. The skew quadrupole correctors provided to correct the effects due to random skew quadrupole field errors in the magnets will be able to correct the linear coupling effects due to the solenoid. It would be worthwhile to do some tracking studies to check for possible non-linear effects due to the solenoid. This requires a more detailed knowledge of the magnetic field shape of the solenoid. A method for describing the non-linear magnetic field of the solenoid, which is convenient for entering it into a tracking program, has been worked out so that the tracking study can be done when the field data becomes available. There are several reasons why tracking studies may be desirable for RHIC. The PHENIX axial field magnet, which appears to have stronger non-linear fields than the STAR solenoid, will also be present. While solenoids and axial field magnets have been used in previous accelerators, RHIC appears to be different as it requires a large aperture and has strong non-linear fields from the accelerator magnets.
