| 内容記述 | TANDETRON II (Model-4130 AMS, HVEE) in Nagoya University is an accelerator mass spectrometer for the ^<14>C dating. Getting over numbers of trouble, the performance test was done in January 1999. However, we could not place it straightway at the regular service, suffering from successive big troubles happened after that test. We restarted the measurement from the beginning of November 1999. After the checking of total systems by HVEE engineer in September 2000 and we applied ourselves to the routine measurement whose procedure was established in 2000. The operation status in 2002 is shown in Fig.1 and Fig.2. The number of targets measured in 2002 was 1003 targets/year or 84 targets/month. In our routine procedure, it takes one week to measure 45 targets (32 samples and 13 standards). Total measurement time was 1545 hours/year and 129 hours/month in that period. The yearly changes in these 4 years are shown in Fig.3. The Generation Volt Meter (GVM) had been making strange noise from end of 2001, and finally its motor was burnt out at the beginning of January 2002. We tried to get a new set of GVM but it takes 3 month, so we decided to repair the motor. We should wait the arrival of motor till the beginng of February, and during the waiting period, we open the tank and check up the diode array of rectifier and found only 2% (30 out of 1422) of diodes were damaged and should be replaced. The other big trouble happened on the high voltage supplier just after replacing GVM system. We found that the both coils of transformer were damaged from the measurement of "Q-Value". We opened the tank again, but the coils looked like no damaging part. Anyway we had to wait till the end of April to get a new set of coils. We could not made almost any measurement during January to May. It is since 7 years from the installation of the machine, or 5 years from the starting of its practical service. Hereafter, we should be careful to the deterioration or the aging of each part, to hold the machine ever in good condition. More careful and foreseeing measures of maintenance should be devised to avoid any destructive trouble. We aim to measure steadily target-by-target as carefully as possible to fit the condition of each sample, rather than forcing to increase a number of measured targets. | |||||
