From today’s 9 o’clock meeting

RHIC unreliable in heat

Multiple problems with RHIC have kept us from running for almost an entire week
Many of these problems heat related
Wolfram Fischer said we should probably not run if temperature > 85 F

MVTX background:

try aggressive collimation at end of this store (the one that came in at 11am), so around 7pm
beta* change: we will run a test tomorrow morning to increase beta* to 5 m (currently beta* = 0.7) in order to decrease background from the triplets as much as possible
There is an existing ramp with this beta* in both IRs
