The goal of the Sealab/bERLinPro project is to build a new generation superconducting RF electron accelerator at HZB. Na-K-Sb photocathode deposited on Mo plug is chosen for this application for its high QE at green laser, long dark lifetime and high thermal stability.
Currently, Na-K-Sb photocathodes are produced in UHV preparation chamber at photocathode lab. In the contribution, we will...
High-brightness electron sources are crucial for applications like X-ray free electron lasers (XFEL), ultrafast electron diffraction (UED), and electron ion colliders (EIC), etc. At Peking University, the DC-SRF gun operates reliably at a low emittance mode of 0.54 mm·mrad(normalized) with 100 pC bunch charge at 1 MHz repetition rate, and a high current mode of 37 pC at 81.25 MHz (3 mA). The...
Semiconductor Cs-Te photocathodes are essential components in high-brightness electron sources, playing a pivotal role in the operation of large-scale accelerators. However, their operational lifetime and efficiency remain critical challenges. To address these challenges, we explore two complementary approaches to enhance photocathode performance and longevity: First, we analyze the systematic...
