Outline of Final Research Achievements |
Micro-calorimeter operated at room temperature has been developed for measuring the pulse energy of free electron X-ray lasers. The size of the micro-calorimeter is of 2.2 cm in diameter and 2.1 cm in length, whereas the previous calorimeter is of 10 cm in diameter and 20 cm in length. The performance test of the new calorimeter was carried out using a synchrotron radiation with 3 keV - 5 keV. The statistical variation of the measurement is confirmed to be about ±1μW, which is compatible to our cryogenic radiometer. The absolute value of the incident radiation power measured by the micro-calorimeter agrees with that by the cryogenic radiometer.
