Spot Sizes Table: SpotsForBeamSettings.csv

Empirics, such as P2, P25, Median, P75 and P98 were obtained directly from the data. These may not be accurate if the beam is larger than the sensor.

To better describe these cases, fit values were obtained with a curve fit to a normal distribution. This can also be inaccurate, as many beam settings aren't normal and the automatic fit might have failed. A goodness-of-fit will be added to each row in the distant future

Setup 1 (on 20.10.2019):

  • With Cividec

  • Position: beam center, ch3 (diode 1) in front, ch4 (diode 3) in the rear

  • RMS: ca. 23 mV, 24 mV

  • Trigger on Ch3: ca. 250 mV

  • Osci amplitude/div: 200 mV or 800 MeV, 400 mV for lower energies

 

Setup 2 (on 20.10.2019):

  • Same as setup 1 but 1 cm to the top from beam center

 

Setup 3 (on 25.10.2019):

  • Same as setup 1 but with Osci amplitude/div: 1V

 

Setup 4 (on 25.10.2019):

  • No Cividec

  • Postion: Same as setup 1

  • RMS: ca. 0.3 mV, 0.3 mV

  • Trigger: 3 mV

  • Osci amplitude/div: 10 mV
