14.30 Saved nnaida1-16 ASIC + Waveform configurations to directory (Data Base Key)

           2015Feb23-12.11.40

          (directory aidas1:/MIDAS/DB/EXPERIMENTS/AIDA/2015Feb23-12.11.40)

          nnaida 1-2, 5-6, 9-10, 13-14 positive input ( front p+n junction strips )

          nnaida 3-4, 7-8, 11-12, 15-16 negative input ( back n+n ohmic strips )

 

           Standard ASIC configurations except

          - shaping time 0xb (6,5us)

          - peaking time 0x8 (16us)

         - slow comparator 0x10 (~160keV)

         - fast comparator (LEC/MEC) 0xff

         - fast comparator (HEC) 0xff

 

          nnaida 1-2, 5-6, 9-10, 13-14 negative input ( AIDA ASIC preamp output inverts input,

                                                                                 i.e. preamp with positive input produces negative input for sampling ADC )

          nnaida 3-4, 7-8, 11-12, 15-16 positive input

         Standard Waveform configurations except

         - threshold 1000

         - pre-trigger 0x100

         - all channels disabled

 

         2015Feb23-12.11.40 is now the default configuration file

 

Note:  The directory (Data Base Key) which will contain the saved settings is created uid: npg, gid: npgstaff, perms 755.

However, its contents are written uid: nfsnobody, gid nfsnobody, perms 777. The default directory (Data Base  Key) permissions

do not work - it is necessary to change the directory (Data Base Key)  to perms 777 after its creation and before saving the

individual FEE64 configuration directories/files to it.
