Zusammenfassung:	The present invention concerns a treatment device comprising a pulsed particles accelerator and a processor for controlling the latter for delivering a treatment plan by deposition at HDR of charged particles into a flash volume (Vht) by PBS. To shorten the time for depositing a target dose (Dti) into the cells spanned by the flash spots (Si) of the flash volume (Vht), the flash spots are combined into k sets of n flash spots (Si). After depositing a jth pulse dose (Dij) into the cells spanned by a ith flash spot (Si) the beam commutes from the ith flash spot (Si) to a next (i+1)th flash spot according to a flash scanning subsequence to deposit a jth dose into the cells spanned by each of the subsequent flash spots of the flash scanning subsequence, until returning to the ith flash spot to deposit a (j+1)th dose (Di(j+1)), and so on When all the cells spanned by all the flash spots of a set have received their corresponding target dose, the beam moves to a next set of combined flash spots and repeats the foregoing pulse deposition steps.
