Most likely data package was lost between the detector and the server. If this was a single occurence, reboot the server and detector and restart Camserver. If it happens multiple times, most likely a data cable is not meeting the specifications. This can be due to minor damages or wear not visible from outside. Make sure that:
If problems persist, contact Support with the error output and a description of when it occurs and with what frequency.
No physical link between detector and detector server.
Check that:
If the above does not solve the issue, contact Support with a photo or output of error and the network Settings (ifconfig output).
Verify with an oscilloscope that the trigger pulse is present and that the high level is higher than 2.1 V.
Never exceed 5 V!
Check the Tech Specs for more details. The PILATUS EXT IN (Trigger Input) is terminated with 50Ω, your trigger source must be able to drive that load.
In any case, check that the detector entrance window is not damaged. If it is, power off the detector and contact Support
If only a single module is affected:
If the entire detector is affected:
Yes. To write e.g. that only the det user gets read and write permissions (600, rw - -) please add the line "umask 077" to the .bashrc in the /home/det directory.

EIGER detectors only support in-vacuum operation if ordered as such. For more information please refer to our documentation.
For in-vacuum operation of the detector the following conditions must be fulfilled:
Condition | Range |
Chamber pressure during operation | > 10^+3 mbar or < 10^-2 mbar |
Chamber temperature during operation |
+10° to +25°C |
Chamber temperature during “bake-out” (unpowered) |
max. +60°C (for temperatures > 40°C make sure the cooling unit is set to +40°C and running) |

If the problem persists send the rest_api log and time of incident to our support team.
Send a request to our support team for further analysis along with following information:
Try following steps:
If the problem persists, send the rest_api.log to our support team.
After the exposure has ended no data was written or submitted. Make sure to check the following points:
If the problem persists, send the corresponding logs (stream, rest, monitor, filewriter) to our support team.
Yes. The module specific data is stored directly in the modules. Modules can be connected to any DCS.
The default setup is not designed for vacuum operation. However, we are able to construct a specific solution tailored specifically to your experiments.
Please contact us with a description of your experiments and requirements for a nonbinding discussion.
If you experience any issues with the signal quality, please send a detailed error description, all experimental parameters, the MYTHEN settings as well as the raw data to our support team.
The general settings which influence the recorded data are the flatfield correction, count rate correction, the threshold settings, and the energy settings (trimming). Please refer to the manual for a detailed description.
Try pinning the current DCS IP. If there is no response, confirm that:
The DCS is delivered either with DHCP running or a static IP (default 192.168.0.90). The initial configuration of your system is described on the system information sheet under the keyword IP-Address. If your DCS is configured with DHCP running or you have manually changed the IP settings ask your IT administrator for the current IP address. The MAC-address and the hostname of your DCS are noted on the system information sheet with the keywords MAC-address and hostname.
In case you do not know your former IP settings you can revert to factory settings. Please proceed as described in the section "Factory Reset" in the MYTHEN2 manual.

In case the ACT LED on the DCS should blink continuously at a high frequency, the flash memory might be corrupted. Please follow the FAQ article [MYTHEN] flash DCS.

The general guidelines are:
Photon Energy [keV] | Trim Settings |
5 - 7 | TrimCr |
7.1 - 12 | TrimCu |
12.1 - 17.5 | TrimCu & threshold 50% |
>= 17.6 | TrimMo & threshold 50 % |

Flashing the MYTHEN DCS is required in case you want to revert to factory settings or the flash memory has corrupted. The flash process can be performed using a virtual linux machine which is provided in the following download links. Please follow the instructions to re-flash your system:
REQUIREMENTS:
HOW TO:
cd /home/det/Desktop/axis/devboar<wbr></wbr>d-R2_10
su
source init_env
cd /home/det/Desktop/axis/devboar<wbr></wbr>d-R2_10/
boot_linux -F -d eth0 -i fimages/fimage_0xff
boot_linux -F -d eth0 -i fimages/fimage_XXX
After flashing, the following access credentials apply:
