This means that the observatory’s new brain, which will be able to analyze more data from the antenna receivers, is going from strength to strength for the future of ALMA.<\/strong><\/p>\n

While Band 2 had previously had a PDR, aligned to WSU specifications (wideband sensitivity upgrade), the ATAC is the first component that is unique to WSU and designed from the ground up for its requirements.<\/strong>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,2_3″ _builder_version=”4.19.1″ _module_preset=”default” min_height=”90.8px” custom_margin=”|auto|6px|auto|false|false” custom_padding=”||1px|||” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_3″ _builder_version=”4.17.4″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/alma.loadingediciones.cl\/dev\/wp-content\/uploads\/2024\/08\/Alvaro-Gonzalez-e1724247848724.jpeg” title_text=”\u00c1lvaro Gonz\u00e1lez” _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][et_pb_column type=”2_3″ _builder_version=”4.17.4″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text admin_label=”Text” _builder_version=”4.19.1″ _module_preset=”default” text_text_color=”#000000″ text_orientation=”justified” custom_padding=”||0px||false|false” global_colors_info=”{}” theme_builder_area=”post_content”]\u201cThese are the first critical projects for the basic implementation of WSU, and the fact that they have passed their corresponding review means that the design is maturing and has entered the critical phase,\u201d says \u00c1lvaro Gonz\u00e1lez, our Deputy Director of Development.<\/strong> [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.19.1″ _module_preset=”default” text_text_color=”#000000″ text_orientation=”justified” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]Landing these requirements was by no means an easy job.

A dedicated working group began refining the initial requirements after a Second Generation Correlator conference in Charlottesville in February 2022 and went through several iterations in order to meet the System Technical Requirements Reviews before delivering their preliminary design.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_2″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/alma.loadingediciones.cl\/dev\/wp-content\/uploads\/2024\/08\/IMG_8138-scaled.jpeg” title_text=”IMG_8138″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/alma.loadingediciones.cl\/dev\/wp-content\/uploads\/2024\/08\/IMG_8139-scaled.jpeg” title_text=”IMG_8139″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_3,1_3″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”2_3″ _builder_version=”4.19.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.19.1″ _module_preset=”default” text_text_color=”#000000″ text_orientation=”justified” custom_padding=”||16px|||” global_colors_info=”{}” theme_builder_area=”post_content”]\u201cThis is the first PDR of a development project initiated to implement WSU.

Juande assures that this work with ATAC will be useful as a template for the next preliminary reviews. \u201cWe have done all the preparations in advance of how the operation is going to be.
