- * The weak link is too weak. For the first experiments we
- will use a simple copper sample holder, and use the sensor
- on the mixing chamber.

- On the mixing chamber, there is a bolt with an M5 thread
- (on the sample container a 7 mm deep hole with an M5 thread is needed).
+ * The weak link was too weak, and there was no spacer on it.
+ We have shortened the weak section and put a spacer above
+ it.

+ * The gauges G1 and G2 do not work reliably. As a workaround,
+ the (earlier unused) G3 gauge has now a connection to the
+ beam dump.
