Compact Superconducting Synchrotron Radiation Source.

Pulsed Vuv Synchrotron Radiation Source

The conceptual design of the pulsed VUV synchrotron radiation (SR) source is reported. This machine has modi®ed racetrack shape (diamond shape) and consist of two superconducting bending magnets, two normal conducting bending magnets, iron yokes, quadrupole magnets and injection system. Maximum magnetic ̄ux density is 7 T. Injector is 100 MeV racetrack microtron and 100 MeV, 10 pps electron bea...

Brightness Temperature Constraints to Compact Synchrotron Source Radiation Obtained from IDV and VLBI Observations

We discuss the observational and theoretical constraints on the brightness temperature of compact opaque synchrotron sources. We consider the implication of observed apparent velocities on the amount of Doppler boosting and compare this with values deduced from directly measured brightness temperatures from ground and space based VLBI observations, as well as the implications of intraday variab...

Ten Years of Compact Synchrotron Light Source Aurora

From mid 1980’s, we have been developing compact SR rings named AURORA. The first one, AURORA-1 (A1), which employed a superconducting magnet to make the ring as compact as possible, has unique features came from its constitution, one circular 360° bending with no focus magnets. After observed first SR in 1989, we continued to improve the whole system, then transferred to Ritsumeikan Univ. in 1...

Mono-Energy Coronary Angiography with a Compact Synchrotron Source

X-ray coronary angiography is an invaluable tool for the diagnosis of coronary artery disease. However, the use of iodine-based contrast media can be contraindicated for patients who present with chronic renal insufficiency or with severe iodine allergy. These patients could benefit from a reduced contrast agent concentration, possibly achieved through application of a mono-energetic x-ray beam...
