Electronic Log for Sonia Escribano

To Do

• Port Saad's FPGA data replay code to Python → copied
• Duplicate functionality of Fern's GUI in D3.

Knowledge Transfer

1. Scintillators

The main properties of our scintillators are:

• ρ = (1.03±0.01)g cm-3
• decay constant = 2.5 ns
• maximum emission at 425 nm (blue-violet)
• light output = 56% of anthracene
• n = 1.57

In total we have 302 scintillator sheets. Their production mechanisms and average thicknesses are summarised in this file []. The order in which the scintillators are assembled in each stack is available in the GUI, inside every experimental run log.

• Each sheet thickness is measured in 8 different points of the scintillator: 4 corners, and 4 middle parts of each side.
• The uncertainty is simply calculated as the standard deviation.
• For the scintillator stacks used in Manchester and PARTREC we measured the thickness in 3 points.
• Clear polished scintillators (machine block) offer the best light output.

GUI

• Modify code to give - instead of 0 when fit not performed ✓
• Plot data with 20 points ✓
• Upload files to new directory
• Modify position of error bars ✓
• x-axis zooming problem: only some numbers work ✓
• Fix misalignment between PDdata and FITdata ✓
• Test access from NUC PC

Replay + Fit

• Check parameter limits with Saad
• Fit data with 20 points instead of 10 to avoid harsh lines ✓
• Print date and time of original file, not produced ones ✓
• Create only one calibration with backST and frontST
• Test code on NUC PC
• Add fitted rate to header ✓

Done

• PARTREC pictures uploaded to: /unix/pbt/data/partrec/20221125/Pictures
• Cut Mylar foil sheets for Manchester experiment
• Talk to Derek about Mylar foil.
• Probation meeting with Simon (fill form)
• Set up new MacBook Pro: might need dual booting (talk to Tony Hoare about Windows).
• Set up Geant4 simulations of detector → copied and running

Quick-start

• Get user name + email ✓
• Get ID card: book appointment online ✓
• Mandatory safety training courses: Safety Induction + Fire Safety ✓
• Book departamental safety induction with Lee Bebbington ✓
• Mandatory training courses: GDPR, information security, freedom of information, DSE, diversity, unconscious bias, ✓
• Create a wiki account ✓
• Register for an account on the HEP Linux cluster (email support@hep.ucl.ac.uk) ✓
• Install Geant4 (instructions: [1]) ✓
• Set up bank details online on myHR ✓
