摘要：
A cooling system for the first crystal of a double-crystal monochromator for a 60-period soft x-ray undulator at the Photon Factory is newly designed and installed. In order to keep smooth movements of the original mechanism in a high-vacuum chamber, heat pipes and a liquid-metal bath are utilized. A fear for melting of an InSb crystal and the instability caused by warming of mechanisms have vanished and significantly improved energy resolution of 5000-8000 is achieved by Si crystals for high photon flux of about 10(11) photons/s in a beam size of 3 x 3 mm2 at a sample position with the cooling system.
