continue...the same set up as before:

The distances are the same:

between PS1 and PS2: 8 cm
between PS1 and n's: 2.5 cm
between PS2 and n's: 1.5 cm
between PS1&2 and n's PMT: 80 cm

But now I am going to increase the power supply for HAMAMATSU, adjust threshold and see what happens.

The powers are:

PS1 and PS2:  -1000 V
n's: -1100 V

The thresholds were:

PS1 and PS2:  -80 mV
n's: -60 mV

Let see what we have. First he CF-243 source is far far away (sealed in the safe):
