Another solution is the very high v

Another solution is the very high voltage solution. Under the very high voltage solution, the HV bias applied across the detector between the cathode and the anodes is increased significantly, relative to normal operation conditions, to produce a relatively very high electrical-field in the detector. Using such an approach, under a relatively very high electrical-field even a hole cloud that has generally low mobility may have sufficient drift time to allow the hole cloud to reach the cathode before being recombined and thereby reduce or eliminate the dependency of the signals of the anodes on the DOI.
