    • Chris continues brazing brass straps. The quality has been improved. We have many brass assemblies now.
    • DSG:
      • About 700 ESR foils (SICCAS) have been preshaped. Start preshaping foils for CRYTUR crystals (after 900 foils for SICCAS are produced). Need new cutting template.
      • Crystal wrapping is very slow, only about 15 crystals have been wrapped during this week.
    • Production of Silicon cookies at the GWU [1]. See Olga's report. Contract with the GWU is under preparation.
    • Igal: continues wrapping ESR for crystals and Tedlar
