AGENDA • Old issues • Recent usage • Special setups
OLD ISSUES • Efficiency improvements are needed • Maintenance time is too large • Need feedback on program balance. Rebalance from 40% Capability, 20% Quality, 10% Reproducibility, 10% Stability, 20% Photon? • Program goals are out of date • TTO • Special setups • LCLS2 studies

From Run 12 Call for proposals: LCLS is currently developing “two color” opera?ng modes, where pairs of FEL pulses are produced with about 1% photon energy separa?on, in both the hard and soE X-ray regimes. We will accept proposals u/lizing two color opera/on. A polariza?on control undulator is planned to be installed in the LCLS this fall and will provide arbitrarily polarized radia?on with limited intensity in the soE x-ray regime. Please contact the respec?ve instrument e- mail address listed above for updated performance parameters as you prepare your proposal.
• To some extent SS benefit both the particular user and aid the development of a new capability • What are the options? 1. provide as needed out of MD time 2. use users time 3. something in between 4. don’t provide or provide fewer
