Some difficulties in classification:

Disks 12 mm• W/O etching (Solvents) disks 1-65

1. Disk missing: 12 WCA1042. Two same disks: 3_WCA104 (one of two took the missing’s

name)3. Reference disks taken by Sergio

61_WCR62_WCR63_WCR64_WCR65_WCR

• Passivation disks 66-130– Four disks don’t have classification codes: 107, 108, 109 & 110 (From now on spare disks)

• SLAC etching disks 131-195– Reference disks instead of passivation cleaning had SLAC etching: 191, 192, 193, 194 & 195

• PCR SCR (change of code)

Disks 80/85 mm

• W/O etching (Solvents) disks 1-33– OK!

• Passivation disks 34-66– Disk missing: 63_PTH104B– Replacement disk: 72_SCV104B

• SLAC etching disks 67-99– Disks missing: 70_SCV104B & 72_SCA104B

– Replacement disks: 100 & 10115

Compulsory changes according to the firms-universities offers :

After contacting with SLAC and Tsinghua, it was compulsory for the main schedule to be changed to the beside heat treatment processes. Both of them, couldn’t run at 10 mbar Hydrogen pressure. ONLY at 1bar.

Because of the past bad experiences at PVA with Argon partial pressure processes at about 5 mbar (due to plasma formation and burning of the heating insert), proposed to run at the 20 mbar pressure for the Argon process AVAILABLE OFFER.

AVAILABLE OFFER : All the samples must be transferred together, in order to be used together and only for once to the heat treatment cycle of the cleaning of furnace-tool and before each series. Due to the difficulties in the stabilization at 10 mbar, it must be mentioned that the Argon pressure, will be at 5 mbar. The TOTAL OFFER rises to 8.500 € .

Drilling (20-22/4) d=80/85mm

Preparation before the drilling.

The drilling of the RF-disks (opening hole at least d=3mm). Compulsory procedure before the cleaning due to the special clips which are used to handle the disks during the cleaning process

The two views of the two different RF-disks (d=12mm and d=80mm). As it is visible, each disk has a special number on the one side (the other is for the thermal tests.)

A try for the RF-disks, to be categorized to three teams according to the three cleaning procedures. Each disk is installed to a special small bag, according to the cleaning method.

Cleaning procedure :

All the RF disks after the installation to the clean room (after received from Kugler) Classified to special plastics bags (each bag has a special label with a special number) Collected in short teams according to the below schedule and transferred to the

Surface treatments workshop, for the cleaning step.

After the cleaning procedure and the agreement with the firms/universities, all the RF disks would be transferred for the heat treatment procedure, in order to get simulated to each thermal cycle.
