Answer 1

Tg-157

Question 2

Task group for proton including tps

Answer 2

Tg185

Question 3

Explain step for commissioning linac

Answer 3

You want to do absolute dosimeter with ion chambers. They need to be calibrated by accredited national lab then you need to measure all the appropriate factors of correction

Question 4

Name the formaulate for IC to get the right charge measurement fully corrected

Answer 4

M = Mraw Pion Pelec Ppol Ptp

Pion for the recombination of ion,with 2 bias voltage
[1-(Vh/Vlow)^2 ]/ [Mhigh/Mlow - (Vh/Vlow)^2 ]
Pelec : given by the accredited lab if the ic and electrometer were not calibrated together
Ppol:effect of polarization , measure with absolute of (M+ - M-)/(2M+)
Ptp: 273.2+T/273.2+22 x 101.3/P
