Pulse peak spectra of the 3 detectors irradiated having an 241Am α resource. The voltage with the detector was set to optimal value and the information was submit-processed (smoothed) to attenuate the overlap. Insert: Geant four simulation in the incoming α particle spectrum.
Pulse condition for an α particle absorbed in the SCD and PCD detector utilizing the broadband diamond amplifier.
In the sector of single crystal diamond expansion by microwave plasma chemical vapor deposition (MPCVD), advancement of crystal growth rate is still a important challenge, Though corrent superior Vitality density plasma is a ralatively effective strategy. In this particular get the job done, a Distinctive plasma concentrating structure was made through magnetohydrodynamic (MHD) design simulation which then was Employed in The expansion experiment based upon the simulation. The plasma properties were examined by means of spectral Investigation and plasma imaging, and late on solitary crystal diamond samples were synthesized. The simulation effects present that the Main electric subject and electron density under focusing ailments ended up 2 instances bigger than Individuals underneath usual situations. The expansion experiment success display that plasma with higher Electrical power density (793.seven W/cm3) is received under regular microwave power (3500 W) and growth tension (eighteen kPa), that's in step with the design calculation success. We learn that a certain number of nitrogen as opposed to superior energy density expansion ailments can substantially modify the growth morphology and affect the standard of the crystal. With those conclusions, we realize The expansion price of single crystal diamond nearly ninety seven.five μm/h. Diverse in the way to acquire large Electrical power density by expanding The expansion pressure, one crystal diamond might be synthesized with higher Electrical power density below regular development strain and microwave power.
