1.7 MV Tandetron & Microbeam Facility

The 1.7 MV Tandetron accelerator procurred from High Voltage Engineering Europa (HVEE) Netherlands, is a high current medium energy Tandem accelerator, having terminal voltage in the range of 100 KV-1.7 MV, generated by means of SF6 insulated parallel fed Cockroft-Walton type solid state power supply, with a high voltage stability of 30V and low terminal voltage ripple of 25 Vpp. Both these characteristics are essential for microbeam applications. Also the low terminal voltage of 150 KV allows ion implantation experiments, which are not easily possible by belt or chain driven Tandem type accelerators. The accelerator is equipped with a dual source injector system, which includes (i) a negative sputter ion source Model 860C for producing ions of heavy elements and (ii) a duoplasmatron ion source model 358 for producing ions of H and He. The maximum currents obtainable after analyzing magnet are 25 µA for H+, 2 µA for He+, and in the range of 10 to 50 µA for ions of heavier elements. The switching magnet has nine exit ports at angles from +45o to -45o. The mass energy product at 20o is 175 amu-MeV. The heavy ion beam facility with beam scanners has been installed on 20o exit port as shown in the photo. RBS and Channelling setup will be installed on the 45o exit port. In order to ensure long term beam stability needed for micro-beam experiments a 90o deflection magnet having mass energy product of 160 amu-MeV is installed on the zero degree port. 

    Possible experiments with the accelerator:

  1. RBS and Channelling

  2. Proton beam writing (focussing protons down to ~ 400 nm)

  3. Ionoluminescence

  4.  PIXE

  5. ERDA - Forward Scattering



Auxiliary facilites:
  1. Thermal deposition system (Make: Consolidated Vacuum Corporation, New York)

  2. For electrical measurements: Keithley source meter 6430 :

  3. Vacuum and air annealing set up [upto 14000C]

  4. He leak detector

  5. Deionised Water Plant

  6. SPIN Coater
