Marco Lonza – and Elettra Status Tango Meeting, May 26-27, FEL-1 and FEL-1 and FEL-2 Seeded FEL: more compact, narrower bandwidth, control of pulse length and of spectral parameters. Two FELs will cover different spectral regions. FEL-1: based on a single stage high gain harmonic generations scheme seeded by a UV laser will cover the spectral range from ~100 nm down to 20nm. FEL-2: in order to be able to reach the wavelength range from 20 to ~4 nm starting from a seed laser in the UV, FEL-2 will be based on a double cascade of high gain harmonic generation. The nominal layout will use a magnetic electron delay line in order to improve the FEL performance by using the fresh bunch technique. Other FEL configurations are also possible. FEL-1 FEL-2 Seed laser

Marco Lonza – and Elettra Status Tango Meeting, May 26-27, …the 1 st seeded FEL output was observed at 43 nm, on 2010 December 13th. The seeded emission intensity overcomes the spontaneous emission by several orders of magnitude and completely saturates the photodiode. Spontaneous emission from 6 radiators has been measured by a photodiode at various undulator gaps. After that… multiple FEL pulses: time overlap is OK here FEL is suppressed by time delay of the seed single FEL pulse saturates the photodiode seed laser: 260 nm, 160fs, 100 MW e-beam: 200 pC, 3 ps, time- compressed six radiators tuned at the 6 th harmonic (43 nm) First Lasing with CHG

Marco Lonza – and Elettra Status Tango Meeting, May 26-27, 2011 The software configurations of FERMI and Elettra (machine) control room workstations and main servers are now aligned: ubuntu LTS tango and omniorb compiled from sources qtango mysql-5.1 (from ubuntu official repository) We are going to test mysql-5.5 on the HDB exploiting the 'horizontal partitioning' of tables based on time periods Switching to tango of a data heavy application (ex. CCD camera control and display) resulted in a 15 to 20 % improvement of speed performances Notifd daemon running on each host of the FERMI control system alarms need events for working we will use events more and more also for display panels and archiving Notes About Software
