Notes from Local Meeting on April 22, 2004
In attendance: Tim Holmstrom, Lisa Kaufman, Kent Paschke, Ryan Snyder, and Guido Urciuoli
Results from last weekend's data taking
- Lumi Results from 2 runs with 4 cm H running at 50 uA (briefly discussed by Kent from memory)
- lumi widths ~400-600 ppm (normalized asym), not uniform between channels
- any 2 lumi channels' asymmetries are correlated
- Double difference width ~120 ppm
- Perhaps correlation is due to boiling. It seems too large to be an electronics noise effect.
- Linearity of lumi looks good so far.
- Septum Heating - see HAPLOG entry 178
In other news
- Work is coming along to build beam telescope to control location and size of beam waist in the laser room for injector setup.
- The second Ocelot will be arriving soon
- We need to think about what we want shifters to be replaying during HAPPEX, and we need to improve our documentation for things such as running the DAQ, feedback,...
