Information available in the TTF Photocathode Database
This database contains the information on the production, shipments and operations of the Cs2
Te / KCsTe photocathodes used at several facilities: FLASH Linac and REGAE
at DESY Hamburg,
PITZ Facility
in DESY-Zeuthen, NMLand
A0 at FNAL and
APEX at LBNL. From 1998 to 2011, all the photocatodes have been
deposited at LASA Laboratory of
INFN, situated in Segrate, near
Milano, in Italy. Since 2011, two more deposition labs have joined Milano in supporting the production: one at DESY and one at FNAL.
The database organizes all the available information concerning the fabrication of
the cathode plugs, the procedures used to prepare the plugs before deposition
and the information on the photocatodes performances (deposition procedures and
operating records).
To browse the database select a link from the menu on the left or below.
The information is organized according to the following list. Each page displays
brief information on all the objects used for the cathodes and contains an
hyperlink to a datasheet which provides additional detailed information on each
object.
 |
|
Transfers |
Lists all cathode transfers between the laboratories (LASA, DESY/Hamburg and
DESY/Zeuthen). The transferred cathodes are listed for each shipments. |
|
|
Transfer Boxes |
Lists the available transfer boxes used for the cathode shipment between the
laboratories, and their present state. |
|
|
Cathodes |
Lists brief information about all the produced cathodes. |
|
|
Plugs |
Lists brief information about all the manufactured plugs (substrates) used for
the cathode deposition. |
|
|
Rods |
Lists brief information about the metal rods used for the fabrication of the
cathode plugs. |
We are still gathering and organizing all the data for all the cathodes during
their several years of operation. There may be some inconsistencies in the
actual data stored to now. Please report them to us.
