eLow Energy Transfer Particles comparisonCalibrated response of ATLAS-MPX (Czech Metrological Institute) : 60Co - (1.95±0,16)E-10 Gy/track 137Cs - (1.42±0,07)E-10 Gy/track

Simulated response of ATLAS-MPX to LETP particles: Input data for MPX01 from Charlie Young applied by Jaroslav Solc to the

detailed model of ATLAS-MPX response (including all convertors, box, simplified electronics, etc.). The calculated quantities are:

number of particles of each type entered the sensor chip (i.e. particle flux) number of electrons which deposited in the sensor chip energy > 7 keV (i.e.,

number of (registered) tracks; no upper energy limit to treat the particle as LETP so far)

the sum of energy deposited by each electron in the sensor chip (energy > 7 keV, i.e. dose)

Subsequently it is possible to find simulated response: number of electron tracks caused by photons entering the device (i.e. electron

tracks caused by electrons created inside the device) number of electron tracks caused by electrons entering the device dose-to-silicon per electron track

Simulated response of ATLAS-MPX to LETP particles: Number of LETP tracks caused by each type of primary particles entering

the device: 74% of tracks caused by primary electrons 25% of tracks caused by primary photons 1% of tracks caused by primary neutrons

Dose-to-track ratio: 1.82E-10 Gy/track
