[BTeam] testplans for beam studies.

[Mike Spata]

Good afternoon,

We have had an IOT go down and repair work will happen tomorrow. There may be an opportunity to do some beam studies depending on how the repairs are done. If they can work on the failed unit while keeping the rest of the system on line we'll keep running Physics to Halls B, C, D. If the HV deck needs to be taken down to do the work then all halls are down. This would be the opportunity for beam studies. Won't know which direction we're going in until the morning. Stay tuned....

Mike

Subject: testplans for beam studies.

This is what we had on the list. Yesterday, we discussed the possibility of using the 1A sync. light along with rolling the NL crest to look at the timing of the beams. This could be an ATLIS where we exercise it.  Number 6) could go along with this.

The SLM test plan 5),as far as I understand those need to be calibrated? There were questions on the photon optics ? What needs to be done before we can do the actual testplan?

I believe we are done with 3) although Dennis may require time for other tests?

We could also schedule a testplan to measure emittance at the Hall D dumplette. This got skipped when we scaled the machine.


Is there anything else we want to investigate ? If so, write an ATLIS, email me and we will put it on the list.
