Objectives
Determined if the steering magnets of the gun are connected to power supply
1. Physically check looking at wires.
2. Change currents on the steering magnet, and observe position of the beam spot. If changes then, connected.
Tune beam using Linac optics only
Chad will tune up the beam using steering elements which are within the HRRL Linac only.
Determined if the OTR target is centered on the beam line
With all beam line magnets off, observe the beam spot at the OTR target. If the beam is centered on the OTR target, then OTR target MAY be centered on the beam line.
Polarization test
Insert a polarizer film. Take several picture for different orientations without changing beam properties.
Angel is measured with respect to:
| Polarizer Angel | Iamge |
| 200 px | 200 px |
Determined if the quads are centered on the beam line
Turn off all the power supplies for the quads.
Turn on Quad closesst to HRRL
If the beam deflects, try to align quad so there is no deflection
Turn on Quad closest to OTR target
If the beam deflects, try to align quad so there is no deflection
