Research Abstract |
The IRIS-experiment using the windowless solid hydrogen (deuteron) target was conducted at TRIUMF in Canada. The thickness of the solid hydrogen target was 50-100 micron. Hydrogen gas at room temperature was sprayed on the surface of pure silver foil (t=5 micron) at lower than 4 K cooled by the GM-Cryocooler in the vacuum, and the solid hydrogen thin film was created. During this experiment, the beam energy loss in the target was measured and the target thickness was always monitored. Since the target thickness was halved in 8-24 hours, the hydrogen target was re-created. In the case of solid deuterium, the reduction of target thickness could not be observed by the energy loss method.
