All shadow shields which are remotely placed inside the cyclotron during shutdown were inspected by Adam Newsome and Chris Peterson on Jan. 13, 2021.

The inspection consisted of:

• Verifying feet were damage-free, welds intact (note: only outer feet were checked due to the large amount of effort that would be involved in shuffling shields around to check each foot)
• Inspection of lifting eyes
• Tightening all critical bolts - many of these bolts were slightly loosened from years of vibration (approx. 1/4 turn)
• General check for other miscellaneous damage

It is believed that all shields are fully acceptable for use, except ones which are clearly marked otherwise from previous years.

The inspection was prompted by a shield which had significant damage last year which could have resulted in a high-dose scenario if it were to get stuck inside the cyclotron. That shield has since been repaired. It is suggested that this inspection take place once every year or two years.
