Photoinduced trapping of xenon in polymeric films at ambient temperature

Trapping of Xenon Induced in Polymeric Films by UV and X-ray Irradiation

“…In the alternative method which consists of loading the samples with X-rays, a Coolidge-type Au anode X-ray tube operated at 80 kV and 30 mA was employed. 1 The efficiency of the tube was estimated with the empirical relation given in ref 8. A value of 0.88% was found from which an X-ray emission power of about 20 W was deduced.…”

“…In a recent paper, 1 we presented a new technique that allows the storage of noble gases in polymeric films at ambient temperature. The trapping of the rare gases in the polymer was realized via X-ray irradiation of the gas and the polymer film.…”

“…2 Initial tests have been performed with hard X-rays (up to 80 keV) by irradiating the polymeric samples with the bremsstrahlung of an X-ray tube. 1 This technique has two principal disadvantages. The first one resides in the long irradiation time needed to obtain a saturated sample (several days), whereas the second concerns the cost of the "loading device" which requires high-power X-ray tube equipment.…”

“…For these reasons alternative methods were probed. Tests with low-energy electrons produced as a result of electric discharges in the noble gas 1 proved to be unsuccessful. Further attempts with UV radiation were found, however, to be very promising.…”
