R&D on laser plasma based accelerators started in India only in the beginning of this century. Both experimental and theoretical studies on laser plasma interaction have been performed at various national labs and universities. High-power Nd:Glass laser systems were developed at RRCAT, Indore. In 2006, a CPA-based 10 TW Ti:Sapphire laser system was set up at RRCAT, for laser plasma interaction...
In 2021, the Chinese ADS Front-end demo superconducting radio-frequency (SRF) linac, known as CAFe, successfully conducted a commissioning of a 10 mA, 200 kW continuous wave proton beam. During this commissioning, it was observed that the SRF cavity fault played a predominant role, contributing to approximately 70% of total beam trips. Upon the detection of fault signals, an acquisition...
SRF technology using niobium accelerating cavities enables high performance and efficient acceleration for modern accelerator projects. While electron linacs accelerate particles with common structures designed for relativistic acceleration hadron linacs require acceleration over a broad velocity range. SRF technology is now being adopted at hadron energies in some cases starting from the RFQ...
Since its completion in 2017, the new 160 MeV proton injector for the CERN accelerator complex Linac4 has undergone some tests to assess and improve reliability, until being connected to the Booster ring during the 2018-22 LHC shutdown. The performance requirements for the LHC high-luminosity upgrade have been successfully met, and during its first two complete years of operation the new...
HIAF is a heavy ion accelerator facility in China for nuclear physics research. The superconducting LINAC was used to accelerating beam energy up to 17MeV/u, then injecting to a Booster Ring. The linac are under construction since 2021, which includes 30 quarter-wave resonator (QWR) and 66 half-wave resonator (HWR). The first-batch production of cavity system have been completed. And the...
We report on the successful test for locating diamonds in ore by using an electron linac to create the 11C isotope atoms via the (gamma,n) reaction which has a large cross-section (8mb) at the Giant Dipole Resonance. The 11C atoms can be detected consequently using the Positron Emission Tomography (PET).
The technology is presently being scaled up for deployment in a mine with the goal of...
