Abstract
An irradiation facility developed to irradiate many different samples simultaneously is described. As a radiation source an electron Van de Graaff accelerator (0.5-2.5 MeV and 0-250 mu A) is used. The beam is deflected by means of a magnetic X-Y deflection, including a cycle slipping facility. The area of the target is 18*18 cm2. The target consists of an array of 15 subtargets, which can be operated at different temperatures between 20 and 175 degrees C. In each of the subtargets 24 samples can be accommodated, i.e 360 samples can be irradiated simultaneously. Differential scanning calorimetry (DSC) and optical absorption results for pure NaCl are presented.
