Effects of<Emphasis Type="Italic"> B</Emphasis>-fields in the Proton Detection Channel of an IEC Device

Proton detection in an IEC device is a complicated task because, unlike the neutron detector, it has to be shielded from X-rays and electrons. Owing to the fusion proton’s short range in matter the proton detectors are placed in the vacuum environment of the device. Also, the proton detectors are vulnerable to damage if exposed to excess light or electrons. The detector is shielded from the light using a Pb shield and, to reduce the electrons reaching the lead shield, a B-field is used. However the B-fields also influence the protons reaching the detector, and hence a good design for the magnet placement is required. In the present paper we investigate the effects of various B-field configurations on the proton detection.
