| Outline of Final Research Achievements |
As a feasibility study of a compact high-voltage TEM using a superconducting RF cavity, computer simulation was given to a specially designed cavity in which two modes were simultaneously excited, TM010 and TM020. The results showed the suppressed energy dispersion and the optimum parameters of both modes to obtain the best performance. A photo cathode of GaAs was prepared and a beam diagnostic system was also assembled. The test cavities were fabricated and cooled not only to measure the cavity performance but to establish the RF and frequency tuning system to obtain the TM020 frequency of just double of that of TM010. At a same time, the basic design of a cryostat was carried out.
