keyword=H-arm Q1 smoking
At 14:45, a large quantity of smoke eminating from a cylindrical vessel above hadron arm Q1 was noticed. Gary Dezern (the on-call tech) was paged and is on his way in. He suspects the pressure relief value, but the cause of this is currently unknown. (This smoke/vapor has been present for at least 20 minutes.) MCC and cryo group have also been notified. Meanwhile progress on target changeover is still underway.
