Muon Unscripted Testing: ARGUS

Introduction

These tests will look at double pulse data. This is when the same sample is exposed to two sequential pulses. It is possible to fit to both pulses simultaneously. The fitting function, \(f\), as a function of time, \(t\), obeys

\[f(t) = f(t+\Delta),\]

where \(\Delta\) is the time between the first and second pulse.

Single Pulse Test

Time required 5 minutes

  • Open Muon Analysis (Interfaces > Muon > Muon Analysis)

  • Change Instrument to ARGUS, found in the Home tab

  • Load run 71799

  • Go to the Grouping tab

    • click Guess Alpha, should get 0.95

  • Load the next run

  • Go to the Fitting tab

    • Add a StaticKuboToyabeTimesExpDecay and FlatBackground

    • Click the Fit button

  • Expected Values are (similar):

    • A: 0.13

    • Delta: 0.52

    • Lambda: 0.11

    • A0: 0.07

Double Pulse Test

Time required 5 minutes This users the same sample as the single pulse test

  • Open Muon Analysis (Interfaces > Muon > Muon Analysis)

  • Change Instrument to ARGUS, found in the Home tab

  • Load run 71796

  • Set to Double Pulse

  • Go to the Grouping tab

    • click Guess Alpha, should get 0.93

  • Load the next run

  • Go to the Fitting tab

    • Add a StaticKuboToyabeTimesExpDecay and FlatBackground

    • click the Fit button

  • Expected Values are (similar):

    • A: 0.12

    • Delta: 0.55

    • Lambda: 0.13

    • A0: 0.09

  • These values are slightly different from the single pulse results

  • Load run 71796

  • Go to the Home tab

    • Change back to Single Pulse

    • Untick the Time zero and set the value to 0.493

  • Go to the Grouping tab

    • Click Guess Alpha, should get 0.91

  • Load the next run

  • Go to the Fitting tab

    • Click the Fit button

  • Expected Values are (similar):

    • A: 0.12

    • Delta: 0.59

    • Lambda: 0.14

    • A0: 0.1
