AB  - A qualitative study on the performance of cylindrical vacuum photodiodes (VPDs) 
      for x-ray detection in plasma focus device has been carried out. Various 
      parameters of VPD such as electrode's diameter, electrode's separation, and its 
      sensitivity are experimentally tested in plasma focus environment. For the first 
      time it is found experimentally that the electrode-separation in the lateral 
      direction of the two coaxial electrodes of cylindrical VPD also plays an 
      important role to increase the efficiency of the detector. The efficiency is 
      found to be highest for the detector with smaller cathode-anode lateral gap (1.5 
      mm) with smaller photo cathode diameter (10 mm). A comparison between our VPD 
      with PIN (BPX-65) diode as an x-ray detector has also been made.
