| Abstract | The Low-Energy Beam Transport (LEBT) section is the part of the injector which transports the beam from the source to the Radio Frequency Quadrupole (RFQ). Its main purpose is to match the beam to the acceptance of the RFQ. The electrostatic gridded lens is an alternative to the more commonly used Einzel-lens or solenoid. It is especially well suited in the scope of designing a LEBT for the carbon RFQ as it only minimally increases the transverse beam emittance. This note presents the design of the gridded lens for the carbon RFQ LEBT and the crosscheck of the beam dynamics results with two independent particle tracking codes. In addition, a sensitivity study to explore the flexibility and demonstrate the capabilities of the gridded lens is performed. |
