Good evening folks! these are the last two #photos from our hike in the #schwarzwald (seen on my blog).
I saw that little stream next to our route and stepped down there to take some photos. The strong highlights in the back made it very hard to take the photos that I had intended. I guess …

Now that we have had our brief bit of fun with the #poolpond, it’s time to drain it so work on completing it can continue! It took just over 12 hours for my little spare pond pump to empty the main pond of about 80% of its water.
It will be empty by morning. I will empty the filter and intake bay as well just to clean everything out. The movement of the past couple weeks through the system will have loosened up a bunch of the gunk still on the various rocks in the filter so a full pump out should remove all that.
I will then concentrate on finishing the piping in the bottom of the main pond for the intake for the second pond and the “periscope” for the bottom returns.
Then I can work on building the rock wall to line the inside of the pond. Or at least experimenting to see if it will work at all!
If it *does* work and I have enough rock to at least start on the bottom layers of the inside wall, then I’ll be able to achieve another milestone: placing the final pebble on the bottom. Important, because that will prevent any groundwater from infiltrating and causing the rubber liner to bubble out.
Really really want to get past that mark before the autumn rains come! For obvious reasons! ☔️
Other jobs that need to be done before winter:
- finish the manifold for the second pump to distribute water to the sprayers and filter and figure out how and where to house and conceal it.
- Dig the electrical trench from the house all the way around the long side of the pond to the back tool shed so we can start wiring it in.
- Clipping the wires on the pumps and adding extension wire to them so they can reach said electrical supplies.
- permanently shore up/modify the borders of the ponds where they were found to be low.
- make a few other minor terraforming modifications for the stream and some of the edges so the water goes a little more where I want it to and a little less where I don’t.

Ultrashort Time-Integrated Diagnosis of Laser-Heated Deuterium Ions in Dense Plasma via Fusion Neutron Spectra
The ultrashort time-integrated diagnosis of ions plays a vital role in high energy density physics research. However, it is extremely challenging to measure in experiment. Here, we demonstrate a reliable approach for investigating the dynamics of deuterium ions in dense plasma. By irradiating a heavy water stream with the hundred Hertz repetitive intense femtosecond laser pulses, the neutrons from D(D,n)3He reaction can be detected via a single Time-of-Flight detector to accumulate the spectrum…
