PbBi PosEventFiles NoGaps 2016
Event files were generated assuming an ideal solenoid having an inner radius of 2.527 cm surrounding a beam pipe with a radius of 1.74 cm. Electrons impinge a 2mm thick PbBi liquid target that has a surface area of 2.54 cm x 2.54 cm. Stainless steel windows 0.25 mm thick sandwhich the PbBi target at locations Z= -10.4875 and Z= -10.7125 cm. The target is located at Z = -10.6 cm and the beam begins upstream at Z = -1.1 m. The incident electron beam is a 0.5 cm radius cylinder.
Positrons exiting the Solenoid
The solenoid design has changed such that the max field is 0.20 Tesla (0.22) and its length is 150 mm.
Event files for positrons and electrons are created at two positions, the exit of the downstream SS windows and the exit of the solenoid.
Twenty (20) million incident electrons with an energy of 10 MeV and forming a cylindrical beam with a 0.5 cm radius cylinder impinged a 2mm thick LBE target located at Z = -106 mm. The Z location of positrons exiting the beam pipe at the end of the 15 cm long solenoid is 44 mm. The positrons are 150.00 mm from the middle of the LBE target (Z=44mm).
A space delimited text file with the above events in the format of
in units of mm for distance and MeV for momentum is located at
for positrons exiting the last SS windows
The Sensitive detector is located either 1.1 mm (Z=-103.775 mm) away from the last SS window or 15 cm (Z= 46.225 mm )downstream.
