Core or cusps: The central dark matter profile of a redshift one strong lensing cluster with a bright central image

Kavli Affiliate: Rafe Schindler | Summary:We report on SPT-CLJ2011-5228, a giant system of arcs created by a cluster at $z=1.06$. The arc system is notable for the presence of a bright central image. The source is a Lyman Break galaxy at $z_s=2.39$ and the mass enclosed within the 14 arc second radius Einstein ring is […]

Equivalent Model of Transient Gyrotron Cathode Response

Kavli Affiliate: Fukun Liu| Summary: The gyrotron is the high power millimeter wave source in the electron cyclotron resonance heating system for the tokamak. The cathode power supply is one of the most important ancillary devices for gyrotron. Some interesting transient phenomena about the cathode voltage and the cathode current was found in the gyrotron […]
