Studies of Sweeper Impact on HMS Optics
NPS configurations: sweeper magnet rotation to reach smallest angles
- NPS configurations (see tables on p.12/13 and NPS layout on pp.14), Feb 2022
- NPS configurations (see tables on p.12/13 and NPS layout on pp.14), Jan 2021
- Illustrations of aperture/acceptance (see p.5/6 and tables pp.22), Feb 2019
Sweeper assembly and Preparation Plan
- Draft of the magnet preparation plan/Field mapping concept
- Sweeping magnet assembly view
- top view, dimensions as required for NPS experiments
Main Coil
Corrector Coil
Yoke
Field calculcations
- TOSCA source file
- TOSCA field results. Grid X -1cm, Y -3cm, Z -3cm. With Z=0 at 157 cm downstream of target, X=0 at small angle side of the magnet gap as shown in figure SAM_coordinates.png
- top view for beam line
- field on the beam line for 6.3 degree NPS position
- field in the main gap for 6.3 degree NPS position
Other Updates
- README instructions for using the code (Gabi)
- Compared to the original version slide #14 has been corrected: The beam deflection angle is much smaller than was shown before and also added a comment about the downstream shielding of the beam line. The original version from 30 July 2015 can be found here
- The coordinate system is based on the magnet, so the target center has the coordinates x = 15 cm, y = 0 cm, z = 157 cm. The beam going to the negative z, positive x at the angle -2.2 degree. The center of the calorimeter is in the direction +4.1 degree from the target.
