CERN Help and Contacts¶
On this page, you can find the contact information for various services and support related to accelerator operations, hardware, and software outside of the OMC-Team. For privacy reasons, only their names are listed here, but you can find their contact details in the CERN phonebook. Most of them are also very active on Mattermost and you can contact them there as well.
Depending on the urgency of your issue, you can also search the Knowledge Base, open a ServiceNow ticket, contact the helpdesk or reach out in one of the dedicated Mattermost channels, which are also listed below.
Maybe also check the Service Status Board to see if there are any ongoing issues with the service you are interested in.
Services¶
This section lists general services that are not specific to a certain hardware or software component.
Normally, each service has a specific ServiceNow form, that you should use to open a ticket, but sometimes it is not obvious which one to use. Remember to that you can always open a general SNOW ticket for any issue, which will be routed to the appropriate service - but this can take longer than opening a specific form.
HTCondor¶
For questions/issues regarding LxBatch/HTCondor the following help is available:
Contact(s):
- Ben Jones
LxPlus/AFS/EOS¶
For questions/issues regarding the LxPlus environment in general or the AFS and EOS file systems multiple contact options are available, but as these commonly experience issues/updates, please first check the Status Board first.
In case you have issues with the file systems, you can also check the Services Portal first, to see if your account is correctly configured. In particular, when running out of AFS quota, you might need to adjust your settings there.

Hardware¶
LHC¶
OP¶
If you are planning an MD session or you have operational questions regarding commissioning, the first person to contact is the EIC during your shift.
That being said, Matteo has always been a close contact for optics related topics in OP, and Michi is also very knowledgeable and involved in this area (see also Software).
As OP is lead by Jörg he is of course also a good contact for general OP questions.
Contact(s):
- Matteo Solfaroli
- Michi Hostettler
- Jörg Wenninger

BPMs (LHC, SPS)¶
In recent years, cooperation between the BI BPM teams and OMC has increased significantly, as they can profit for our measurements and statistical analysis of BPM data quality, and we can use their expertise for BPM related issues and shortcomings, improving the quality of measurements.
Contact(s):
- Manuel Gonzalez Berges
- Michal Krupa
Software¶
A Special Thanks to Michi Hostettler
While not the official support for software, due to his experience, involvment in development and regular use of different tools, Michi Hostettler is incredibly knowledgable and can very often help with questions/issues regarding various software packages used in accelerator operations. If you run into an issue, it is likely he has already encountered it before, and most likely has a solution.
That is to say, if you are reading this, THANK YOU MICHI FOR ALL YOUR HELP in the past, it has been invaluable!

Acc-Py¶
As described in the sections on our python environments and virtual environments, we use the Acc-Py distribution as our main Python environment. This distribution system is maintained by the Acc-Py team at CERN, who can be contacted for questions regarding its usage, installation or development.
Contact(s):
- Ivan Sinkarenko
- Philip Elson
Java¶
Questions regarding the Java infrastructure we are using, like deployment of applications, the CBNG build system or the Acc-Java libraries our software depends on, can be directed to:
Contact(s):
- Felix Ehm
NXCals¶
The NXCals team is always interested in feedback regarding the user experience and use-cases of NXCals, at CERN in general, but also for each individual section - as they might have very different needs.
They regularly organize meetings to gather feedback and discuss new features, so feel free to reach out to the contacts below to be added to the mailing list.
While not directly involved in the development of NXCals, Michi Hostettler is taking care of data collection and organization for the LHC, which is stored using the NXCals framework and is therefore a good contact for questions with regards to that topic.
