February 2006 start of mesaure with the e-meter
measure Energy and Energy Spread for each position Review SPARC

E-meter unistall Docember 2006 unistall of e-meter
January 2007 exposition in the Rome auditorium in the “Festival della scienza” The e-meter is now in the SPARC hall we are different requetst to use in other laboratory Trieste, CTF, Pitz, .... Review SPARC

AFT attenuator test During the first operations we have found some problems with the attenuator; During the e-meter work period we start some test on the attenuator. Review SPARC
9
STATUS of the waveguide power attenuators
● The attenuators have been intensely power tested. ● The design power levels have not been achieved. ● Internal discharges occurred at about 10 ÷ 15 MW input power ● Discharges take place in the circulator section that contains ferrite bars. ● This could be due to excessive outgassing rate of the ferrites under high RF power operation. ● Two units have been already delivered back to the manufacturer ● A meeting with the manufacturer is foreseen next week in Germany S-band waveguide attenuator Review SPARC
10
CIRCULATOR FERRITE BARS 12 MW input power Review SPARC
11
The attenuator have been sent to AFT to solve the problem;
The next week we will go to the AFT to talk about the problem. Review SPARC
12
Wayguide network modification
The problem find with the attenuator have forced to modify the wayguide network. Review SPARC

Alignment The alignment has been executed and has been made a first control after the installation of wayguide and fluid connection The realization of hole for the SPARC Lab laser imply the new test of the posistion The corrector installation wait the end of allineament Review SPARC

Fluid The installation of fluid system is completed
The system is under test The PLC system must include the second accelerator unit solenoids and the corrctor Review SPARC

Review SPARC
37
Magnet Power supplies The solenoids PS is installed and connected
The corrector PS is installed and wait the corrector installation to complete The dipoles PS is under costruction to the first dipole we use a DAFNE PS The quadrupoles PS is under definition for the first 3 quads on the dogleg we use a DAFNE PS Review SPARC

41
The ENEA quads The quadrupoles are positioned and must be allineated
The power supplies are under test in the ENEA lab. Review SPARC
42
Control system The use of the control system has been totally satisfactory; All basic window for the magnet are developed and used Some specific window to use in automati operation with the e-meter are developed; The automatic acquisition are tested; The first version of elctronic logbook are used satisfactory. Review SPARC
43
New feature for the control system
New e-logbook based on SQL database are developed; New class of element are introduced and wait to the with the beam. Review SPARC
44
Diagnostic The image diagnostic are completaly tested;
Toroidal current monitor are tested; BPM are start develop with the hardware; Some new diagnosti are planned and installed just after the gun. Review SPARC
45
Modified desing Original desing Review SPARC
46
RF DEFLECTOR Copper cells and tuners RFD in the LNF oven
-The RF Deflector will be used for longitudinal phase space characterization and slice emittance measurements; -It has been successfully designed and realized and it is now installed in the SPARC LINAC; -The device has been LNF; Copper cells and tuners RFD in the LNF oven Review SPARC
47
RFD under test: before and after each brazing step RF measurements have been performed
RFD installed in the LINAC with cooling system Reflection coefficient at the coupler input port Tuned magnetic field on axis Review SPARC
48
Authorization Request from National Fire Department;
Realization of a secure area in the stairs from SPARC hall and connection tunnel; Installation of fire-plug in the SPARC hall; Close all hole beetwen the different hall; Remove two allineament column behind the gun. Review SPARC
49
Autorization Request from radioprotection; Realization 2 beam dumper;
Closing of all the passages round the clean room; Installation of security switch in the seeding’s clean room. Realization of operation document. Review SPARC
50
Planning End july october 2007
End PLC program to include the second series of solenoids; Connection of all magnets and test of programs; Cabling of all diagnostic system and test Installation alignment of ENEA Quadrupoles PS ENEA allineament Start with accelerator section conditioning. Review SPARC
