Abstract
A 600-MeV electron storage ring has been constructed in only ten months at a cost of 200 million yen at the Electrotechnical Laboratory (ETL) in Tsukuba. The 500-MeV high efficiency-high current electron linac being operated for high energy-dosimetric experiments serves as an injector. The ring consists of eight bending magnets (r = 2m) and four triplets of quadrupole magnet. The circumference is 31.45 m and λ p is 22 Å. The lattice order is O/2 B d Q f Q d Q f B d O/2. The harmonic number is 17. The maximum stored current is 160 mA and l/e lifetime is 1.5 hours at present. The radiation is used for calibrating photometry and soft X-ray standards, photoelectric analysis of electronic materials, and LSI lithography.Keywords
