Kind of neat video some may enjoy. I've been designing and manufacturing electronic instruments for a few years that will go into here (Canada is providing a special calibration system). I posted a picture at the end of my post of the old detector to show how this new one will look once completed....



Machines give scale to the new tank:

Old smaller detector (shows how walls will look once PMTs are installed):

Japan is installing large PMTs (photo multiplier tubes), but Canada, Poland and Italy are suppling special calibration ones with 19 small PMTs in space of one large one. The Canadian ones in particular each contains special light sources. These will be distributed through Hyper-K for calibration purposes. Hopefully making it perform well enough to discover new science (understanding neutrinos, dark matter and dark energy).

It's why I'm not getting much time into my cruiser...lol.

Particles which travel faster than the speed of light in a medium (water) shed light in a cone shape. Sort of like the shock waves (sonic boom) off an airplane when it travels faster than the speed of sound in air. This is called Cherenkov Radiation and is the blue glow you see from the water in a nuclear reactor. The neutrinos when they hit a water molecule have a chance of causing this effect (produced by the secondary charged particle).

So basically Hyper-K is a massive camera (Water Cherenkov Detector). that captures these events (light) with single photon sensitivity and nano second time resolution. Here is how the events look. There is enough info here to figure out the particle/energy/direction, etc.

Our calibration system flashes LED's sub-nanosecond at a known time, which can also be detected by the photosensors. Some are collimated (narrow angle beam) and some are diffuse (wide angle). These are what are used for calibration. Basically expensive one way LIDAR system.

100 billion neutrinos pass through your thumb in one second. But they're incredibly hard to detect. It takes big crazy stuff like this to detect enough for study.

These ones are actually created artificially 300km away on the other side of Japan. We're making another detector there too so we can compare the beam before hand. The neutrinos pass through the ground the entire way. They change flavor which is a part of the puzzle.
 
Wicked Cool, Nick. So much beyond our world of comprehension.
Hey Jon, thanks! I feel very lucky to be able to contribute. Despite high workload, definitely a highlight of my career.
 
Geek level 1000. Uber cool.
 
If anyone has seen the Netflix show "3 Body Problem" there is a scene where someone commits suicide in the old Super-Kamiokande detector. I chuckled, as they portrayed it as being in Europe as part of CERN, but really it's in Japan.

haha, that was the second thing I thought of...first was that cheesy 2012 movie.

Weren't neutrinos basically microwaving the earth's core ?

Plausible AF I'm sure, but I had a lot less issue with that than I did the "hydraulics" on the back door of the ship at the end :lol:
