Minutes for UCL Proton Calorimetry Meeting, 18th July 2017 (D107, Physics & Astronomy, UCL)

Present

Simon Jolly, Anastasia Basharina-Freshville, Ruben Saakyan

RS:

  • PMT bases are on their way from Hamamatsu!
    • Start with testing dynode 4 and 5.
    • Measure peak and average anode current with LEDs.
    • Check low rate performance first, then increase rate to check whether distortion occurs above 1MHz.
    • Gated PMT will require a bit more thought...
  • Scintillator sheets also shipped from Nuvia:
    • Samples of 100x100x10mm, standard and pTP enhanced composition, 0.3mm foil to be cut as needed.
    • Also 3mm pressed material included.
  • WaveCatcher documentation for hardware and software available from Orsay:
    • 2–64 channel versions available.
    • Seems similar to Caen but with access to firmware.

ABF:

  • Applied bias voltage to photodiode preamp: signal increases, so does noise...
  • Will check photodiode with 1–100 ms integration windows.
  • Will also check maximum integration window for Caen DT5740D QDC 16-channel digitiser.

SJ:

  • SMA components mostly here:
    • High quality Huber and Suhner components ordered for proton calorimetry; LOTS of less expensive (but still decent) spares available within group.
    • SMA-BNC and SMA-MCX adapters all arrived.
    • Waiting on 2:1 Mini-Circuits splitter.
    • Various lengths of Huber and Suhner SMA cable borrowed from John Mitchell (UCL Electrical Engineering).
  • Will email Ferruccio Renzoni and Peter Barker regarding coupling of photodiodes to electronics.
  • Will contact Hakan Nystrom at Skandion (Sweden), Claus Schmitzer at MedAustron and Marco Pullia at CNAO regarding possible beam time.
