Info from ELog:
  http://midtwist.triumf.ca:8081/EL/020826.902?exp=twist

The recent runlog entries are accessible on the web from the "runlog"
button on the Elog pages.  The Web access is intended only to have a
look at recent data. It is not made to read huge files.

The runlog is a flat file in 

  /twist/data_onl/current/runlog.txt

You should copy the file /twist/data_onl/current/runlog.txt to your
account and use an editor or scripts to search through it to look for
older information.
