Previous Logbook





  • Turned around drawing updates for a smaller TPC volume (slight reduction of radius), communicated the changes with the worksop
  • More workshop communications and test fitting of components
  • Hydraulic pump for external clamps is waiting on its power plug - has been ordered, cable has been identified
  • Computing
    • Between Patrick and I, we figured out which copy of the DMTPC code is the most recent, turns out (somewhat naturally) that m3daq has the most recent versions of all the code except...
    • DmtpcControl, which is most recent on m3slow
    • We have now merged the two in an external source so that we can start correct version control
    • Identified some of the workings of the SQL database
  • Several rounds of leak checking etc... here is the fun part

  • Complete DMTPC and HPTPC internal comparison drawings, for design consistancy
  • Adriana and I spent a full day preparing/repairing HPTPCs feet, removing burring on the screw threads such that the feet can be put down.
