Application period is open for the CLF Training Weeks, beginning in September 2023. These 2-week courses are designed to provide new PhD students with the necessary skills to participate in high-power laser experiments both here at the CLF, and at other facilities around the world. The training will be specifically tailored towards users of high rep-rate laser systems such as Gemini and EPAC, with a particular focus on management and analysis of large datasets. However, it will also cover skills relevant to any laser laboratory: optical alignment techniques, laser and plasma diagnostics, experimental set-up, and general safety. Dates for the Training Weeks courses are 4th – 29th September 2023, the application deadline is 3rd July 2023.
