- | The middle level is separated into two areas: (1) the beam line section west of the intermediate image chamber, leading to the S800 object box, and (2) the middle level of the spectrograph with the staircase. The button for area (1) can be found at the westernmost end of the vault at the S800 object, where the beam line enters the vault from the transfer hall. This section is locked off from the remaining part by a chain at the intermediate image chamber. Make sure that the lights in this section are off before locking he chain. Area (2) has one button on the frame of the spectrograph, | ||
