====== Jour Fixe ======

kHz, DF, SS, WFP, NJ, PG, FW
====== General ======

  * Windows 10 Upgrade TBD soon!
    * Buy 4 SSDs (Xabbu3, MgControl, Wavemeter, Reslab)
    * Install Win10 + "Only programs you need" freshly on new SSD
      * Disconnect old SSDs (keep as backup)
      * Disconnect (Data) HDDs
        * Will this cause the RAID to die?
        * Will RAID work after that by just re-pluggin the drives?
        * **Make backups** and/or check, if automatic **backups are present** and in the latest state
  * Journal Club
    * NJ will not //volounteer// for the next one -> Next in line would be SS (least amount of JCs: 2)
  * Holidays

====== Resonator ======

  * Got OK for  Comb repair + New PCF
    * TBD: Wirtschaftlichkeitsuntersuchung
  * Maser: Ionpump problems -> Move to PTB over XMas
    * HITec caddy possible -> kHz will ask Tobias for Monday/Tuesday (<span class="timestamp-wrapper"><span class="timestamp">[2019-12-16 Mo]</span></span>/<span class="timestamp-wrapper"><span class="timestamp">[2019-12-17 Di]</span></span>)
  * 10 MHz: Warmup behaviour investigation this week
  * R1: Lock showed 50 Hz/ 100 Hz oscillations two weeks ago -> Rf amplifier or PSU? -> Problem now gone.
  * R2
    * We see modes now!
    * Needs a PDH to work on for a few weeks to make it finally working again after all those years&#x2026;
      * SS to skip PTB work for a few weeks to invest full-time on R2?
      * Ask EMR next week, if SS shall do it or not
  * H-Beast
    * Changed experimental place (Because of SS's leg)
    * Chamber closed (not yet pumped) to mitigate acustics via air
    * Remeasure vibration sensitivity
====== Mg ======

  * Systematics

|Clock AC-Stark|E-17|
|Densitiy|E-16|
|Lattice AC-Stark|E-15|
  * SWAP during ''broken-comb time'' (within DP)
    * Mostly seen heating&#x2026;
    * Reason due to restricted velocitiy classes in the DP?
    * New student (Nishad, opt. technology) going to work on that
      * Exp. and Theory
====== Quenchlaser ======

  * Mode matching improved
  * Temp. of laser housing was bad (was PID-Peltier, now Thorlabs). Still oscillations seen, which cause modejumps
  * Polarization changes infront of transfer cavity seen.
    * Definitely not infront of first fiber
    * Check, if its directly after the first/second/third fiber
