Andreas Lüdeke at the ESLS XX at BESSY Short Pulses at the SLS: low-α Low-α optics established in 2009 α 1 = 3.6 x RMS bunch length 8 ps at 50 mA total beam current (For comparison: 40 ps at 400 mA is normal operation) Interest by 3 out of 18 beamlines Two blocks of 80 hours beam time used in 2010 Insufficient man power at beamlines to prepare and run these experiments Not enough results to justify operating for 3 out of 18 Discontinued 19-Nov-2012Page 11
