-====== BPM (Beam Position Monitor) ======
-===== Libera Platform B =====
-The Libera is a data acquisition and beam position processor system used for the BPM systems in different accelerators and transfer lines. It was developed by the slovenian company [[https://www.i-tech.si|Instrumentation Technologies]] and was adapted and enhanced for FAIR applications as an in-kind contribution. It is a modular [[https://en.wikipedia.org/wiki/MicroTCA|MicroTCA]] based system used in different configurations for the particular requirements of the BPM systems for different accelerators at GSI and FAIR.

-==== Libera Platform B features ====
-Each of our Liberas has some features which are common for each application:
-  * 19“, 2U, 310mm depth
-  * MTCA based (non standard)
-  * COMe Controller Board
-  * FTRN slot
-  * Acts as FEC
-  * Up to 4 BPM modules
-==== Libera family tree ====
-For GSI/FAIR beam diagnostics there are four types of applications:
-  * Libera Hadron for Circular Machines
-  * Libera Hadron for Circular Machines + Closed Orbit Feedback (COFB)
-  * Libera Hadron for HEBT
-  * Libera Single Pass H (SPH)
-{{ :instruments:bpm:libera_family_tree_1_0.png?direct&400 |Libera family tree @GSI & FAIR}}
-Another application for the Libera at GSI/FAIR is the Low Level RF (LLRF) controlling. It is under responsibilty of GSI's LRF department and not further treated in this article.
-The usabilty of a Libera for a certain application depends from the hardware configuration and installed software. We have three types of hardware configurations:
-  * Libera Hadron for ESR, HESR & HEBT
-  * Libera Hadron + COFB for SIS18 & SIS100
-  * Libera SPH for p-Linac
-=== ESR-/ HESR-/ HEBT-Libera (Libera Hadron) ===
-{{ :instruments:bpm:libera_hadron_hebt_front.jpg?direct&600 |}}
-== Inter Connection Board (ICB) ==
-  * COM Express MSC C6B-7S
-  * Intel Core i5-3610ME
-  * 16GB DDR3-1600
-  * GbE, USB 2.0, DVI-A
-  * ARM BMC
-  * FPGA
-=== SIS18- /SIS100-Libera (Libera Hadron + COFB) ===
-{{ :instruments:bpm:libera_hadron_cofb_front.jpg?direct&600 |}}
-=== p-Linac-Libera (Libera SPH) ===
-{{ :instruments:bpm:libera_sph_front.jpg?direct&600 |}}
-For the retrofit the Liberas are also now in use for GSI's SIS18 and ESR.
