  A pulse com­pres­sor is re­quired to com­press the RF power dis­trib­uted to the four ac­cel­er­at­ing struc­tures of a sin­gle C-band (5712 GHz) mod­ule of the Swiss­FEL. The pulse com­pres­sor is of the bar­rel open cav­ity (BOC) type. A total of 26 BOC de­vices are nec­es­sary to op­er­ate the lin­ear ac­cel­er­a­tor (26 mod­ules or 104 C-band struc­tures) of Swiss­FEL X-ray laser. The C-band BOC com­bines the ad­van­tages of com­pact­ness and large RF ef­fi­ciency i.e. large com­pres­sion fac­tor. Key fea­tures of the BOC are de­scribed and how they have been im­ple­mented in the man­u­fac­tur­ing and tun­ing processes. RF mea­sure­ments of the BOC are pre­sented to ac­count for the me­chan­i­cal pre­ci­sion reached by man­u­fac­tur­ing. Up to Au­gust 2014 about 6 BOCs have been man­u­fac­tured in-house and one has been high power tested in a RF test stand to sim­u­late the op­er­a­tion in Swiss­FEL.

  The lin­ear ac­cel­er­a­tor of Swiss­FEL will be based on C- band tech­nol­ogy. This paper sum­ma­rizes the lat­est re­sults that were achieved with the first pro­to­type com­po­nents. Fur- ther­more, the progress and plans of the se­ries pro­duc­tion are dis­cussed.
