“…In the past decade, SINAP-II [15][16][17][18][19] and UVSOR-II have played a pioneering role in the technical development of slant scattering. While UVSOR-II has succeeded in producing MeV gamma rays at limited slant-scattering angles ranging from 70°to 110° [21,22], the gamma-ray beam production at SLEGS is systematically carried out in an innovative manner with a dedicated interaction chamber [23] and double collimator system [24,25].…”

The Shanghai Laser Electron Gamma Source (SLEGS) is a powerful gamma source that provides MeV gamma-ray beams for nuclear science and technology. It was developed as one of the 16 beamline stations in the Phase II Project of the Shanghai Synchrotron Radiation Facility. The slant-scattering mode is for the first time systematically employed in laser Compton scattering at SLEGS to produce energy-tunable quasi-monoenergetic gamma-ray beams. The SLEGS officially completed its commissioning from July to December 2021. Gamma rays in the energy range of 0.25–21.7 MeV with a flux of 2.1 × 104–1.2 × 107 photons/s and an energy spread of 2–15% were produced during the test. This paper reports the results from commissioning the SLEGS beamline.

“…Continuous positron sources from beta decay have limitations such as low intensity and relatively wide angular distribution. In addition, Taira et al (2010) proposed picoseconds positron beam generation from laser-Compton γ rays at 90°collision geometry. Intense relativistic picosecond positron beams at ≥2 × 10 10 positrons/s can be obtained from laser-solid interactions with lasers capable of 10 2-10 3 J/shot (Chen et al, 2011), which is at present still rare.…”

Intense Compton-scattering γ-ray radiation driven by laser wakefield acceleration (LWFA) and generation of ultrashort positron beams are investigated by Monte Carlo simulation. Using an LWFA driven GeV electron bunch and a 45 femtosecond, 90 mJ/pulse, and 10 Hz Ti:Sapphire laser for driving the Compton scattering, fs γ-ray pulses were generated. The latter have a flux of ≥10 8 /s, peak brightness of ≥10 20 photons/(s mm 2 mrad 2 0.1% bandwidth), and photon energy of 5.9 to 23.2 MeV. The γ-ray pulses then impinge on a thin high-Z target. More than 10 7 positrons/s in the form of sub-100 fs pulses at several MeV can be produced. Such ultrashort positron pulses can be useful as the pump-probe type positron annihilation spectroscopy as well as in other applications.
