Besides the exploitation of the Helios 2 superconducting compact storage ring for user operations and for its own R&D work, SSLS envisions a 4th generation synchrotron light source to complement and, eventually, replace the current facility. This vision includes an accelerator system based on a superconducting linear accelerator with up to 5 recirculation loops for energy multiplication and recovery with the distinguishing feature that the light would be generated by superconducting mini- and micro-undulators. Under this programme, SSLS is pursuing the development of superconducting miniundulators including a proof-of-technology electron beam experiment in co-operation with the Shanghai Institute of Applied Physics and the analytical and numerical study of the fabrication tolerances of superconducting miniundulators with respect to their finite length field errors and mechanical errors.

Abstract True Beam medical linear accelerator is capable of delivering flattening filter free (FFF) and with flattening filter (WFF) photon beams. True Beam linear accelerator is equipped with five photon beam energies (6 FFF, 6 WFF, 10 FFF, 10 WFF and 15 WFF) as well as six electron beam energies (6 MeV, 9 MeV, 12 MeV, 15 MeV and 18 MeV). The maximum dose rate for the 6 WFF, 10 WFF and 15 WFF is 600 MU/min, whereas 6 FFF has a maximum dose rate of 1400 MU/min and 10 FFF with a maximum dose rate of 2400 MU/min. In this report we discussed the open beam dosimetric characteristics of True Beam medical linear accelerator with FFF and WFF beam. All the dosimetric data (i.e. depth dose, cross-line profiles, diagonal profiles, output factors, MLC transmission, etc.) for 6 MV, 6 FFF, 10 MV, 10 FFF and 15 MV were measured and compared with the published data of the True Beam. Multiple detectors were used in order to obtain a consistent dataset. The measured data has a good consistency with the reference golden beam data. The measured beam quality index for all the beams are in good agreement with the published data. The percentage depth dose at 10 cm depth of all the available photon beams was within the tolerance of the Varian acceptance specification. The dosimetric data shows consistent and comparable results with the published data of other True Beam linear accelerators. The dosimetric data provide us an appreciated perception and consistent among the published data and may be used for future references.
