The rest of the day was spent changing out the spare X-cooler in the ARPANSA building which has been failing ever twenty two days since we got here. The X-cooler is a refrigeration unit that cools down the gamma radiation detector to minus one hundred and seventy degrees Celsius. So now we take readings every day and monitor the temperature for the next twenty two days and hopefully it won't fail.
After dinner I worked on my blog till very late before hitting the fart sack.
