FYI > Hi everybody, > > it's New Years Eve and guess what: there's a controlled access (right > now). We'll try to keep it short. > > A brief update about the weekend: In general, this weekend was much > better than the last one. Every day had a couple of stores. We had one > experimental access of 2.5 h. Beam intensity could be improved > significantly. Since friday we had 3 ramps with tune feedback working in > the blue ring :) while yellow could not be used due to a hardware > problem. In order to keep working on yellow feedback we needed an access > into sector 2 (going on right now). Once this is done, we don't plan to > open before thursday but continue with production stores. We'll keep > working on ramp tuning for intensities, polarization and emittance > conservation though. > > Due to high luminosity tuning at the expense of polarization, last > weekends polarization was actually > much less than what we've achieved before and we didn't get more than > 15% in RHIC at injection and basically nothing at flattop. In most > stores polarization was even smaller than that. 3 ramps were done with > successful tune feedback in Blue.
