Using 'little block' HV supply. 11&12 with pre-amp ref set at 0x30.</p> <p>The rates are as follows:-</p> <p>nnaida11: 19k</p> <p>nnaida12: 52k</p> <p>nnaida13: 10k</p> <p>nnaida14: 10k</p> <p>The stat spectra of 13 & 14 look ok.</p> <p>The stat spectra of 11 and 12 are strange and noisy but not "mad".</p> <p>Maybe when the power supply filters are in place this can be revisited</p> <p> </p></td> </tr> </tbody> </table> </p><p> </p>
