	The FLASH (Free Electron Laser in Hamburg) facility at DESY (Deutsches Elektronen-Synchrotron) in Germany has been extended by the new undulator line FLASH2 providing twice as many experimental stations for users in the future. After the acceleration of the electron bunch train up to 1.2GeV in FLASH, a part of the beam can be kicked into FLASH2, while the other is going to the old undulator line of FLASH I. The commissioning phase of FLASH2 started in early 2014 and is continued parasitically during user operation in FLASH1. One key point during first beam commissioning is the availability of standard diagnostic devices such as Beam Position Monitors (BPMs). In the last couple of years new electronics for button and strip-line BPMs have been developed, based on the MTCA.4 standard. This new Low Charge BPM (LCBPM) system is designed to work with bunch charges as small as 100 pC in contrast to the old systems at FLASH initially designed for bunch charges of 1nC and higher. This paper summarizes the performance of the BPM system and discusses the applied methods based on beam based correlation techniques to study the system.

The FLASH (Free Electron Laser in Hamburg) facility at DESY (Deutsches Elektronen-Synchrotron) in Germany has been extended by the new undulator line FLASH2 providing twice as many experimental stations for users in the future. After the acceleration of the electron bunch train up to 1.2GeV in FLASH, a part of the beam can be kicked into FLASH2, while the other is going to the old undulator line of FLASH I. The commissioning phase of FLASH2 started in early 2014 and is continued parasitically during user operation in FLASH1. One key point during first beam commissioning is the availability of standard diagnostic devices such as Beam Position Monitors (BPMs). In the last couple of years new electronics for button and strip-line BPMs have been developed, based on the MTCA.4 standard. This new Low Charge BPM (LCBPM) system is designed to work with bunch charges as small as 100 pC in contrast to the old systems at FLASH initially designed for bunch charges of 1nC and higher. This paper summarizes the performance of the BPM system and discusses the applied methods based on beam based correlation techniques to study the system.
