LHC Filling Schemes
LHC Filling Schemes viewer application
To obtain details about a filling scheme, start the LHC Injection Scheme Display
Please note that the to avoid duplications and inconsistencies the old file based repository is now deprecated. All filling schemes must be accessed trough the official Java application.
For backward compatibility theJava application can generate a text file with the usual format for any selected scheme.
Mac users will need to install jws to run any LHC Java application. Find the instructions here: installing jws on Mac.
Guidelines for understanding the filling scheme names:
Base structure: <spacing>_<Nb>b_<IP1/5>_<IP2>_<IP8>_<code>
<spacing> = Single, or 2025ns, or 525ns, or 75ns, or 50ns, or 25ns, etc.. This refers to the characteristic bunch spacing in the main injector batches used for the given filling scheme. Single means that single bunches are injected into the LHC.
<Nb> = total number of bunches per beam for the given filling scheme (normally, identical for both beams). If a probe bunch is kept (i.e. not overinjected), it is not counted in the total number. The presence of a non-overinjected probe bunch is encoded in the suffix <code>.
<IP1/5> = expected number of colliding bunch pairs in IP1 (or IP5) for the given filling scheme
<IP2> = expected number of colliding bunch pairs in IP2 for the given filling scheme
<IP8> = expected number of colliding bunch pairs in IP8 for the given filling scheme
<code> = a free suffix to encode variants of a filling scheme
