D423800100014 FACILITY (CYCLO,2BLGVUB) D423800100015 SAMPLE (54-XE-124,ENR=0.9922) D423800100016 Highly enriched 124Xe gas (>99.92% of Xe present, D423800100017 all other Xe isotopes <0.01%) at absolute pressure D423800100018 between 0.28 and 0.86 bar. D423800100019 DETECTOR (HPGE) D423800100020 METHOD (ACTIV,EDEG,EXTB,GSPEC,STTA) The cells were D423800100021 irradiated with proton beams of 150 nA intensity at D423800100022 37.5, 29.0, 22.4, 16.0 and 13.0 MeV primary energies. D423800100023 One or two cells were placed in a closed cylindrical D423800100024 metal holder which served as a Faraday-cup for the D423800100025 initial beam current measurement. In front and at the D423800100026 back of each cell 12.05 or 25 mm thick Ti foils were D423800100027 attached to monitor the beam. At the end of the D423800100028 bombardment the irradiated gas cells were first D423800100029 allowed to cool for a couple of minutes. Afterwards D423800100030 the closed cells are placed in an ice-water bath at D423800100031 0 C for 5 min to allow settling of the produced Cs and D423800100032 I isotopes onto the wall of the chamber before D423800100033 starting the measurements. At the end of the D423800100034 measurement cycle the enriched 124Xe gas was D423800100035 cryogenically recovered.
