Electrostatic septum for "Continuous Transfer" from PS to SPS

For "Continuous Transfer" to the SPS, the PS beam, after acceleration, is peeled off in 5 turns. To minimize losses, the magnetic septa are preceded by an electrostatic septum in straight section 31. We see the inner part of it, on a lab-bench. The first part consists of W-wires, the second part is a Mo-foil. The circulating beam passes through the opening, the ejected beam at the outside (above the wires, in this picture). This assembly is the anode-part, the cathode is not shown.
