Zibi, Rachel, Mike, Suwat, Jack, Bill, Betty, Bec; Dan is sick

• Bec: Miniball: O ring is being made, Andy Thulin is working on it
• Ordered a wheeled cart and golf cover for it
• Rachel: HiRA parts cleaned, Jimmy will assemble next week and show to Bill and Betty
• Zibi: Room 127: new plan. Requested exhaust for pumps, eyewash, old HiRA source box behind door, food shelf outside. The schedule says we should be moving mid-March
• Lee/Alan's experiment: no updates on their electronics. Preamp boxes: Lee can build but we need to provide instructions, can use to put in our HiRA preamp boards between flanges and motherboard
• Right now the preamp boxes are designed to connect the flange to the motherboard
• don't want to remove HiRA preamps from motherboards
• Do we have an appropriate flange in storage? It is likely.
• Mike: correction to Z>2 particles using Tianxiao's light output formula. Looks good! Next need efficiency correction

• Pass the name of the chain.. the program plots theta vs phi
• Program is designed for HiRA but should work for LASSA.
• Makes filled bins =1
• Project onto x (theta) axis, then scale by 1/sin(theta)
• To get absolute efficiency, Jack will output instructions to manipulate to true efficiency.
• Jack will update more next week.

• Looking at t/3He
• Lab: now has energy cuts. Efficiency changes with energy: see more high-energy particles at smaller angles
• Correction: area of bins/4Pi plotted by theta vs energy
